Steps use checkbox (`- [ ]`) syntax for tracking. + +**Goal:** Introduce an internal, immutable, structural `BsonPath` value class and a `BsonPathParser` for the JSONPath subset we plan to support. **Zero production callers in Phase 0.** Wiring happens in later phases. + +**Architecture:** A pure value type plus a recursive-descent parser. Both live in +`phoenix-core-client` and are package-public so later phases (canonicalizer, compile, +IndexMaintainer) can use them. No Phoenix runtime is touched. + +**Tech Stack:** Java 8 (Phoenix targets 1.8 source), JUnit 4 (Phoenix's existing test framework). + +--- + +## Calibration vs. spec + +Verified against the codebase before writing this plan: + +- The blanket "JSON fragment" guard in `MetaDataClient` (`isJsonFragment`) **only fires for + `JsonQueryParseNode` / `JsonModifyParseNode`** (`ExpressionCompiler.java:313`). It does **not** + fire for `BSON_VALUE` or `JSON_VALUE`, so those indexes are **not** blocked today. Phase 2 will + verify and lock down behavior on top of that. +- Phoenix grammar does **not** define Postgres-style `->` / `->>` operators today. Phase 1's + canonicalizer will target the function-call surface that exists: `BSON_VALUE(doc, '$.a.b', + 'VARCHAR')`, `BSON_VALUE(doc, 'a.b', 'VARCHAR')`, and `JSON_VALUE(doc, '$.a.b')`. Adding `->` + /`->>` is deferred (out of scope for this feature). +- `BSON_VALUE`'s third argument already carries the SQL type name. The spec's "mandatory `AS + `" requirement is therefore satisfied by the existing `BSON_VALUE` arity. Phase 4 adds + optional grammar sugar; v1 reuses the existing function call shape. + +Phase 0 itself does not depend on any of the above — but later phases do. Carrying the calibration +here so the implementer can follow the chain. + +--- + +## File Structure + +- **Create** `phoenix-core-client/src/main/java/org/apache/phoenix/parse/bson/BsonPath.java` — + immutable value class.

`rejectsLoneDollar` should pass already; `rejectsNegativeIndexLooksLikeWildcard` likely +fails because `-` triggers an `expected ']'` after the digit-loop. + +- [ ] **Step 3: Tighten parser to make all negatives pass** + +Update `BsonPathParser.parsePath()` to handle the leading-bare case explicitly: reject `null`, +empty, leading `.`, etc. If any test from Step 2 fails, fix the parser to make it pass without +breaking earlier tests. Common fix: reject `pos < input.length()` after the main loop only when +input is consumed. + +Specifically, before `parsePath()` returns, if `pos != input.length()`, raise: +`throw new BsonPathSyntaxException("unexpected trailing input", pos);`. But this is already +covered because the loop only exits when `pos == input.length()`. The `rejectsTrailingChars` +test is therefore sensitive to whitespace/space handling — your parser will hit ' ' inside +`parseDotField` because ' ' is not `isIdPart`, so the loop ends at the space.

Parsed from a path string (`$.a.b[0]['k']`). Carries a + structural representation (list of segments: field, array-index, quoted field). +- **Not a SQL column type.** It is never exposed as a user-visible `PDataType`. It exists + to serve as the canonical form inside `BsonPathParseNode` and as the argument normalizer + for `BSON_VALUE`. +- **Equality:** structural. `$.a.b` and `$."a"."b"` compare equal. `toString()` emits the + canonical spelling (dot-notation where legal, bracket-quoted otherwise). + +### 2. `BsonPathParser` + +- **Location:** `phoenix-core-client/src/main/java/org/apache/phoenix/parse/bson/`. +- Accepts the JSONPath subset: dot segments (`$.a`), array indices (`[0]`), quoted keys + (`['weird key']`, `["esc\"key"]`). Leading `$.` optional. +- Rejects with a specific `SQLException`: wildcards (`$.*`, `$[*]`), filters (`$[?(...)]`), + recursive descent (`$..x`), slice syntax (`$[0:2]`). + +### 3. `BsonPathCanonicalizer` + +- **Location:** `phoenix-core-client/src/main/java/org/apache/phoenix/compile/`. +- **Signature:** `ParseNode rewrite(ParseNode input)`. +- **Inputs recognized (all rewritten to `BSON_VALUE(doc, BsonPath('$.a.b'))`):** + - `BSON_VALUE(doc, '$.a.b')` — no-op, validate path. + - `BSON_VALUE(doc, 'a.b')` — missing leading `$.`. + - `doc -> 'a' -> 'b'` and `doc -> 'a' ->> 'b'`. + - `doc ->> 'a.b'` (Postgres-style single-string path). +- **Contract:** pure function; does not consult schema; safe to run on any `ParseNode`. +- **Non-recognized shapes** (function-wrapped LHS, `CAST(BSON_VALUE(...) AS ...)` on the + WHERE side) pass through unchanged — the query will simply not match a BSON-path index. + +### 4. DDL relaxation — `MetaDataClient.createIndex` + +- Replace the blanket `isJsonFragment` rejection at `MetaDataClient.java:1735` with a + **deterministic-function allowlist**: + - Allowed on index expressions: `BSON_VALUE`, `BSON_VALUE_TYPE`, `->`, `->>`, and their + canonical form. + - Any other JSON/BSON function: rejected with the existing error. +- Determinism check at `MetaDataClient.java:1741` is unchanged — `BSON_VALUE` and operator + sugar are `PER_ROW` deterministic, which passes the existing gate. +- Canonicalization: the compiled `Expression` for the index column is rewritten through + `BsonPathCanonicalizer` before being persisted into `SYSTEM.CATALOG`. This guarantees + catalog-level deduplication of equivalent expressions. + +### 5. DDL grammar — mandatory `AS ` and reserved `USING PATH` + +- Extend the `indexed_column` grammar rule so that when the expression contains a + recognized BSON path operator/function at the top level, an `AS ` clause is + **required**. Missing the clause raises a compile-time error: + `"BSON path index expressions require explicit type: AS VARCHAR|BIGINT|..."`. +- `AS ` applies a `CAST` to the evaluated expression before it becomes the index key. + Coerce failures fall through to sparse-null handling (see §6). +- Parse but reject `CREATE INDEX ... USING PATH (...)`: reserved for a future multi-valued + variant. Error: `"USING PATH is reserved for a future release."` + +### 6. Sparse-null in `IndexMaintainer.buildRowKey` + +- In the existing per-expression evaluation loop (around `IndexMaintainer.java:840-870`), + after `expression.evaluate(...)` returns, if the resulting `ptr.getLength() == 0` AND the + expression is marked as a BSON-path expression (a new per-column flag on + `IndexMaintainer`'s serialized metadata), **skip this row's index update** — do not emit + a put or a delete to the index region. +- Why gated on a flag: today a null result in a normal expression index produces a + `null`-keyed entry. We preserve that behavior for non-BSON expressions (backward + compatibility). + +### 7. Predicate rewrite — `IndexStatementRewriter` + +- Before `IndexStatementRewriter` runs its exact-AST map lookup, invoke + `BsonPathCanonicalizer` on both (a) every indexed expression in the index metadata + (once, on load) and (b) each predicate `ParseNode` in the `WHERE` clause. +- Canonical LHS → look up in existing `indexedParseNodeToColumnParseNodeMap`. +- Supported predicate shapes in v1 (RHS must be a literal or bind parameter): + - ` = ` + - ` IN (, ...)` + - ` <|<=|>|>= ` + - ` BETWEEN AND ` +- Unsupported shapes fall through to existing behavior (full scan). +- Feature flag: `phoenix.index.bson.rewrite.enabled` (default `true`). + +### 8.

The spec just needs to be grounded in +actual Phoenix behavior rather than assumed behavior before it's ready for dev@. + +Feedback is ordered by severity. + +--- + +## Major problems + +### M1. The motivation's cornerstone claim is wrong + +The spec says `MetaDataClient.createIndex` rejects "any index expression containing a JSON +fragment" at L1735 (motivation #1). Verified against +`ExpressionCompiler.java:313-315`: + +```java +if (node instanceof JsonQueryParseNode || node instanceof JsonModifyParseNode) { + this.isJsonFragment = true; +} +``` + +The guard triggers **only** on `JSON_QUERY` and `JSON_MODIFY` — **not** on +`BsonValueFunction`, `JsonValueFunction`, `BsonValueTypeFunction`, or any other BSON +function. So the premise that a blanket guard blocks BSON-path indexes today is +incorrect; `CREATE INDEX ... (BSON_VALUE(doc, '$.a.b'))` probably already parses and +compiles. The real motivation is different: **there is no canonical form for +predicate-matching, and there is no type-safe key-extraction surface**. The spec must be +re-anchored on those, not on a guard that doesn't exist. + +Fix: rewrite Motivation #1. Keep the allowlist idea (for `JSON_QUERY` / `JSON_MODIFY`, +which really are blocked), but stop calling it "the first blocker." + +### M2. Phoenix has no `->` or `->>` operators + +The spec repeatedly treats `doc->'a'->'b'` and `doc->>'a.b'` as user-facing syntax Phoenix +already accepts. Grepping the ANTLR grammar and `FunctionParseNode` / operator classes +returns nothing for arrow operators. Phoenix surfaces BSON navigation only through +`BSON_VALUE(doc, path)` / `BSON_VALUE_TYPE` / `BSON_CONDITION_EXPRESSION`. + +Consequence: half of the `BsonPathCanonicalizer`'s declared inputs are grammar-extensions +in disguise, not canonicalization. Adding `->` / `->>` is a separate grammar change with +real design questions (operator precedence, overload with arithmetic `>`, PG-compat +semantics, dictionary-vs-array semantics of `->>`). + +Fix: either (a) drop `->` / `->>` from v1 scope and canonicalize only across `BSON_VALUE` +call-shape variants (path with/without `$.`, equivalent quoting), or (b) add an explicit +"Grammar additions" section that owns the arrow-operator design. Don't hide it inside the +canonicalizer. + +### M3. Sparse-null semantics are incorrect for UPDATEs and DELETEs + +Section 6 ("Sparse-null in buildRowKey"): + +> if the resulting `ptr.getLength() == 0` ... **skip this row's index update** — do not +> emit a put or a delete to the index region. + +This is a correctness bug. Scenario: + +1. Row has `doc = {"a":{"b":"x"}}`. Index has entry `("x", pk)`. +2. UPSERT changes `doc` to `{"a":{"c":"y"}}` — path `$.a.b` is now absent. +3. Under the spec's rule: we see empty `ptr`, emit no delete → **stale index entry + `("x", pk)` is left behind forever.** + +Correct semantic: on sparse transition to absent, the index entry from the pre-image +**must** be deleted. For transition from absent to present, emit a put. The write path +must read the pre-image (which sync global already does in `IndexRegionObserver`), +evaluate the path on both pre- and post-image, and emit: + +| Pre-image | Post-image | Action | +|---|---|---| +| present, value v1 | present, value v2 (≠ v1) | delete v1, put v2 | +| present, value v | present, value v | no-op | +| present, value v | absent | delete v | +| absent | present, value v | put v | +| absent | absent | no-op | + +Spec needs a new subsection "Index maintenance under update/delete" that spells this out, +and the phase-2 IT must cover all five transitions. + +### M4. `ptr.getLength() == 0` is the wrong null signal + +In Phoenix's scan machinery an empty `ImmutableBytesWritable` is sometimes null and +sometimes a legitimate zero-length value (e.g., empty `VARCHAR`). Using length 0 to mean +"absent path" loses the distinction between `$.a = ""` and `$.a` missing, and the +canonical form's return type (VARCHAR) makes empty-string a legitimate row that the index +should cover. + +Fix: use an explicit `NULL` tri-state. `BsonValueFunction.evaluate` needs to distinguish +"path missing / coerce failed" (→ don't index) from "path resolved to empty string" (→ +index as empty string). Currently `BsonValueFunction` doesn't do that — another reason +the write path is more than a "one-line branch." + +### M5. PostgreSQL `->>'a.b'` is not a nested path + +The canonicalizer claims `doc ->> 'a.b'` canonicalizes to `BSON_VALUE(doc, '$.a.b')`. In +PG, `->>` takes a single key, so `doc->>'a.b'` looks up a field whose literal name is +`a.b`, not a nested path. If Phoenix adopts `->>` with PG semantics (which M2 hasn't +decided), this rewrite is semantically wrong; if Phoenix invents its own `->>` that splits +on `.`, that's fine but must be documented as a deliberate divergence. Either way the +current spec conflates the two. + +### M6. Predicate rewriter runs on every query's WHERE — latency tax + +`IndexStatementRewriter` fires on every select. Adding BSON canonicalization to the hot +path means every query pays a cost for a feature most tables don't use. + +Fix: fast-path — skip canonicalization if the statement's resolved tables have no BSON +columns, or no BSON-path indexes. Spec should acknowledge this and call it out as a +required optimization, not "wire it in." + +### M7. `isStateless()` and `getDeterminism()` are unverified assumptions + +Spec: "`BSON_VALUE` and operator sugar are `PER_ROW` deterministic." `BaseExpression +.getDeterminism()` defaults to `Determinism.ALWAYS` and `BsonValueFunction` doesn't +override. `ALWAYS` passes the gate, but the spec's wording ("PER_ROW deterministic") is +factually off and also suggests the author didn't check. More important: +`MetaDataClient:1751` also rejects `expression.isStateless()` expressions. A `BSON_VALUE +(doc, '$.a.b')` with the path as a literal string — is the expression itself considered +stateless by Phoenix's definition? Needs verification. If it's stateless, the allowlist +relaxation isn't enough. + +Fix: run a 20-minute spike — try `CREATE INDEX idx ON t(BSON_VALUE(doc, '$.a.b'))` today, +see what actually fails. Rewrite the motivation based on what actually fails, not what the +spec assumes. + +--- + +## Moderate problems + +### Mod1. Duplicate-index deduplication is an upgrade hazard + +Because `PColumn.getExpressionStr()` stores the canonical form, two pre-existing indexes +that today have distinct expression strings (e.g., one created with `'a.b'`, one with +`'$.a.b'`) will, after upgrade, canonicalize to the same string. Behavior is unspecified: +SYSTEM.CATALOG PK collision, silent drop of the second, or a new deduplication error on +upgrade? + +Fix: describe the upgrade path explicitly. Options: (a) canonicalize only on new CREATE +INDEX, leave old entries alone; (b) run a one-shot metadata migration at upgrade time +with conflict detection. + +### Mod2. Index maintenance read amplification for partial UPSERTs + +Phoenix UPSERTs can touch a subset of columns. If the user UPSERTs a column other than +`doc`, index maintenance still needs to know whether `doc`'s current value at the path +matches the previous index entry. Sync global does pre-image reads for expression indexes +today — but BSON pre-image reads fetch potentially large cells per index. The spec +doesn't cost this or discuss the pattern. Users will see p99 write latency rise on wide +BSON documents. + +Fix: add a "Write-path performance" subsection. At minimum, name the read amplification; +at best, provide an INCLUDE-style opt-out (maintain lazily via async rebuild when the +BSON cell isn't in the mutation). + +### Mod3. INCLUDE of a large BSON doc isn't free + +Section 8 says "honor existing INCLUDE clause." INCLUDE copies the cell bytes into the +index region. For a 1MB BSON doc with 10 BSON-path indexes, that's 10MB of index payload +per row. Phoenix has no existing size guardrail. + +Fix: spec should either warn + cap, or say explicitly "this is the user's choice" and +provide a `phoenix.index.max_include_cell_size` safety valve. + +### Mod4. Sort order mismatch between SQL type and BSON native type + +The user-declared `AS BIGINT` or `AS VARCHAR` drives comparison, but the underlying BSON +value at the path may not be that type. With sparse-skip on coerce failure, correctness is +preserved — but users writing `WHERE BSON_VALUE(doc, '$.x') > 10` on an `AS VARCHAR` +index will get string lexicographic order, not numeric order, and queries like `WHERE +... > '9'` will return rows where `$.x = '11'`. This is PG-compatible behavior but users +are going to file it as a bug. + +Fix: spec should mandate a warning in the EXPLAIN output when an inequality predicate +runs over a VARCHAR-typed BSON path index; and/or recommend indexing numeric paths +explicitly as BIGINT / DECIMAL. + +### Mod5. Feature-flag granularity + +`phoenix.index.bson.rewrite.enabled` as a global flag. One rewriter bug disables the +feature cluster-wide. A per-index property (stored in `SYSTEM.CATALOG` as a table-level +option like `DISABLE_ON_REWRITE='TRUE'`) lets an operator surgically park one index. + +### Mod6. `is_bson_path` protobuf flag is redundant + +If the `Expression` in IndexMaintainer is known to be rooted at `BsonValueFunction` +(post-canonicalization), the IndexMaintainer can inspect the expression directly. Adding +a protobuf bit adds a second source of truth that can drift. Simpler: make the behavior +fall out of `expression instanceof BsonValueFunction` (or a marker interface +`ISparseIndexed`). + +--- + +## Minor / nits + +### N1. Line numbers will rot + +`MetaDataClient.java:1735`, `IndexMaintainer.java:840-870` — both correct as of today's +master, but specs age poorly when pinned to line numbers. Reference by method name +(`MetaDataClient.createIndex` — the `isJsonFragment` check) instead. + +### N2. `BsonPath` location + +`phoenix-core-client/.../schema/types/` is a `PDataType` home. `BsonPath` is not a +`PDataType`. Move to `parse/bson/` (where the parser lives) or `util/bson/`. + +### N3. `AS ` is grammar, not "extending indexed_column rule" + +Section 5 calls it "extending the rule." Be explicit: this is a grammar change to +`CreateIndexStatement.g` (or equivalent) that introduces a new optional (for regular +columns, mandatory for BSON-path expressions) `AS ` production. + +### N4. Phase 4 reserves `USING PATH` after Phase 3 has already shipped the feature + +Reserving a keyword after users are live is mildly risky (compatibility surface). Move +keyword reservation into Phase 2 so it lands with the DDL changes, before anyone writes +queries against the feature. + +### N5. Phase 5 "within agreed budget" with no budget + +Pick a number now. Suggest: < 10% write-path p99 overhead on a workload with a single +BSON-path index on a 4KB BSON doc, and < 5% query p99 overhead on queries against +non-BSON-indexed tables (the tax from M6). + +### N6. No mention of salted tables, multi-tenant views, transactional tables, local indexes + +Phoenix has four orthogonal index modes + salting + tenant views. Spec needs a +compatibility matrix even if the answer for several is "not supported in v1" — currently +they're simply invisible. + +### N7. `phoenix.index.bson.sparse_skips` needs a per-index dimension + +A single cluster-wide counter doesn't help an operator debugging one misbehaving index. +Tag the metric with `table` and `index`. + +### N8. Diagrams repeated + +The Architecture diagram and the Data-flow diagrams say the same thing twice. Collapse. + +### N9. "Zero production callers" as Phase 0 exit criteria + +Good, but also add: no references from `main` source at all — the class should be +package-private and unused until Phase 2. + +### N10. No rollback story for Phase 2 past the flag + +If a bad canonicalization in Phase 2 writes garbage into `SYSTEM.CATALOG.EXPRESSION_STR`, +flipping the flag off doesn't heal the catalog.

End-to-end + working feature. +- **`BSON_VALUE(doc, 'path', 'TYPE'[, 'default'])` already takes type as an argument.** + `BsonValueFunction.java:67-75` declares three required args plus an optional default. + Type coercion at eval time is already implemented across VARCHAR, INTEGER, LONG, + DOUBLE, DECIMAL, BOOLEAN, VARBINARY, DATE, BSON. +- **Null / missing-path is already handled correctly.** `BsonValueFunction.evaluate` + calls `returnDefaultValue(ptr, type)` when the path is missing. With the default + `'null'` (string) it sets `EMPTY_BYTE_ARRAY`. Phoenix's index-key encoder in + `IndexMaintainer.buildRowKey` (around the separator-byte logic at + `IndexMaintainer.java:890`) already honors `ptr.getLength() == 0` as a null marker and + strips trailing nulls. +- **Partial index (`WHERE path IS NOT NULL`) is the existing idiom for sparse-index + semantics** — visible in `Bson5IT.java:112,116`. Users who want "only index rows where + the path is present" write the partial-index `WHERE` clause today. +- **Pre-image / post-image diff is already implemented** in + `IndexRegionObserver.generateIndexMutationsForRow` (L1265-1310). It computes + `buildRowKey(currentDataRowVG, …)` and `buildRowKey(nextDataRowVG, …)` and emits a + delete for the old key when the new key differs. Update, delete, and absence-transition + transitions work for expression indexes out of the box. +- **Both STRONG (sync) and EVENTUAL consistency modes exist** — `IndexConsistency.java` + and used in prod IT with `CONSISTENCY = EVENTUAL`. +- **`INCLUDE(doc)` syntax already honored** on BSON-path indexes (`Bson5IT.java:378`). +- **Index types:** `GLOBAL`, `LOCAL`, `UNCOVERED_GLOBAL` (`MetaDataClient.java:1446, + PTable.IndexType`). BSON-path indexes in prod tests use `UNCOVERED INDEX` with + `CONSISTENCY = EVENTUAL`. +- **The `isJsonFragment` guard** (`ExpressionCompiler.java:313-314`) triggers only on + `JsonQueryParseNode` and `JsonModifyParseNode`, not on `BsonValueFunction`, + `BsonValueTypeFunction`, or `JsonValueFunction`. It was never a blocker for BSON path + indexes. The original spec's Motivation #1 was wrong. +- **Determinism and stateless gates pass naturally.** `BsonValueFunction` extends + `ScalarFunction → FunctionExpression → BaseCompoundExpression`, whose default + `getDeterminism()` combines children (→ `Determinism.ALWAYS`) and whose default + `isStateless()` is AND of children (→ `false`, because the BSON column reference is + non-stateless). Both gates in `MetaDataClient.createIndex` (the determinism check and + the stateless check) already pass for BSON path expressions. + +### Real gaps that remain + +These are the verified gaps — the legitimate feature work: + +1. **No path-string canonicalization.** `IndexExpressionParseNodeRewriter.leaveCompoundNode` + matches ParseNode by `equals()`. `FunctionParseNode.equals` compares name + children; + a path literal child is a `LiteralParseNode` whose `equals` is byte-for-byte on the + value. So `BSON_VALUE(doc, 'a.b', 'VARCHAR')` and `BSON_VALUE(doc, '$.a.b', 'VARCHAR')` + — which are semantically identical — do **not** match the same index. A user whose + query spells the path one way misses an index created with the other spelling. +2. **Predicate matching limited to exact equality in practice.** In-tree IT coverage + (`Bson5IT`) shows `BSON_VALUE(COL, p, t) = ?` hitting the index. Range (`<`, `<=`, + `>`, `>=`), `BETWEEN`, and `IN` are not exercised — and because the rewriter relies on + AST equality of the indexed expression against the predicate LHS, range predicates + *will* rewrite correctly for the indexed column (that part is generic scan-range + derivation), but canonicalization differences will still cause misses. +3. **Sort order for typed numeric paths is likely wrong with the default index column + type.** `BSON_VALUE(doc, 'x', 'VARCHAR')` returns VARCHAR bytes — fine. But + `BSON_VALUE(doc, 'x', 'DOUBLE')` at the write path sets `ptr` to + `PDouble.INSTANCE.toBytes(double)` (IEEE 754 bits), which is **not** order-preserving + under unsigned byte comparison for negative values. Range scans on such indexes will + return incorrect ordering across sign boundaries. Must be verified; if confirmed, + fixed at index-key time with a sign-flip or by routing through Phoenix's fixed-width + numeric encoders that already provide order-preserving bytes. +4. **Rewriter has no fast-path.** `IndexStatementRewriter.translate` runs on every + `SELECT`, walking the index column list and parsing every indexed expression. On + tables with no BSON columns and no BSON indexes, this is pure overhead. It does not + scale as BSON indexes proliferate. +5. **No operator sugar.** Phoenix exposes BSON navigation only through `BSON_VALUE`, + `BSON_VALUE_TYPE`, `BSON_CONDITION_EXPRESSION`. There is no `->` or `->>` in the + grammar (`grep` of `PhoenixSQL.g`, `PhoenixBsonExpression.g`: no hits). Adding them is + a self-contained grammar change independent of the indexing work. +6. **Observability is thin.** No per-BSON-index metrics for rewrite hits/misses, no + EXPLAIN hint showing which canonical path matched, no counter for partial-index + skips. Operators debugging "why didn't my query hit the index" have no signal. + +## 2. What this design delivers + +A focused, incremental enhancement program that closes the five real gaps above without +inventing new infrastructure where Phoenix already has working infrastructure. + +### Non-goals (unchanged from prior spec, reaffirmed) + +- Dynamic-column (per-row, non-schema) indexing. +- GIN-style multi-valued path indexes. +- Containment (`@>`) predicates. +- Wildcards, filter expressions, recursive descent in JSONPath. + +### Goals, restated + +1. Queries that spell a BSON path in a different-but-equivalent way must hit the same + index as the DDL that created it. +2. Range (`<`, `<=`, `>`, `>=`), `BETWEEN`, and `IN` predicates on BSON-path expressions + must use the index correctly, including with correct sort order for numeric types. +3. The rewriter must add negligible overhead on queries against tables with no BSON + indexes. +4. Operators must be able to tell whether and why an index was used. +5. The DDL / query experience must remain backwards-compatible — nothing in `Bson5IT` + breaks. + +## 3. Architecture + +Two modest additions, both client-side; no on-disk format change; no coprocessor change. + +``` + ┌───────────────────────────────────────────────┐ + DDL │ Parser ─► BsonPathNormalizer (new) ─► compile │ + │ │ │ + │ ▼ │ + │ canonical path literal stored in │ + │ PColumn.getExpressionStr() (SYSTEM.CATALOG) │ + └───────────────────────────────────────────────┘ + + ┌───────────────────────────────────────────────┐ + Query │ Parser ─► BsonPathNormalizer (same rewriter) │ + │ │ │ + │ ▼ │ + │ IndexExpressionParseNodeRewriter │ + │ (fast-path: bail if no BSON indexes) │ + │ │ │ + │ ▼ │ + │ existing exact-AST match ─► scan ranges │ + └───────────────────────────────────────────────┘ +``` + +`BsonPathNormalizer` is applied at two points: (a) during `CREATE INDEX` compilation, +before the expression string is persisted into SYSTEM.CATALOG, so equivalent paths +produce identical expression strings; (b) during query rewrite, to the WHERE-clause +parse nodes, so a differently-spelled path rewrites to the canonical form and then +matches by `ParseNode.equals`. + +Everything else — `IndexMaintainer.buildRowKey`, `IndexRegionObserver.preBatchMutate`, +partial-index `WHERE` compilation, `CONSISTENCY` modes, `INCLUDE` semantics — is reused +without modification. + +## 4. Components + +### 4.1 `BsonPathNormalizer` + +- Location: `phoenix-core-client/src/main/java/org/apache/phoenix/parse/bson/`. +- A pure function that walks a `ParseNode` tree and, whenever it finds a + `BsonValueParseNode` whose **path literal** (second argument) is a constant string, + replaces that literal with the canonical form of the same path. +- Normalization rules (v1, JSONPath subset): + - Strip a leading `$.` or `$` if present (Phoenix's `BSON_VALUE` uses paths *without* + the `$.` prefix — confirmed by `Bson5IT.java:111` which uses `'rather[3].outline. + clock'`, no leading `$`). Accept both forms on input; emit no-prefix form. + - Collapse redundant whitespace inside segments (none legal today, so mostly a no-op). + - Normalize quoted keys: if a quoted key matches the unquoted-key regex, drop the + quotes (`['a']` → `.a`); otherwise keep exact bracketed form. + - Reject wildcards (`*`), filter expressions (`[?(...)]`), recursive descent (`..`), + and slice syntax (`[a:b]`) with a clear SQLException that identifies the offending + segment. +- Does **not** touch the first argument (the BSON column) or the third/fourth arguments + (type, default). Those must match byte-for-byte between DDL and query, as today. +- Does **not** consult schema. Pure syntactic. +- Unit-tested with golden files covering equivalent path pairs. + +### 4.2 Fast-path guard in `IndexExpressionParseNodeRewriter` + +`IndexExpressionParseNodeRewriter`'s constructor today parses every index column's +expression string (`IndexExpressionParseNodeRewriter.java:62-75`). For a table with ten +BSON-path indexes, that's ten `SQLParser.parseCondition(...)` calls per query. + +Change: + +- Add a `hasBsonIndex` check on the index `PTable` at construction time. If no index + column has a `BsonValueParseNode`-rooted expression, skip the BSON normalizer + invocation on the WHERE clause entirely. This is the M6 fast-path from review. +- Populate the existing `indexedParseNodeToColumnParseNodeMap` with the *already-canonical* + ParseNode (see §4.1); when normalizing the WHERE clause, look up by canonical form. + +### 4.3 Numeric sort order verification + fix + +This is the one place where existing production behavior is likely wrong and we must +change real code. + +For `BSON_VALUE(doc, 'x', 'DOUBLE')` used as an index key, the write path currently +routes through `BsonValueFunction.evaluate` → `PDouble.INSTANCE.toBytes(double)`. This +uses `Double.doubleToLongBits` raw bytes; they are **not** order-preserving under +unsigned byte comparison across sign boundaries (negatives sort *after* positives). The +same issue applies to `PFloat`. `PInteger`, `PLong`, `PSmallint`, `PTinyint` use +Phoenix's offset-encoded integers which *are* order-preserving. `PDecimal` uses its own +encoding which is order-preserving. + +**Action:** + +1. Write a unit test that creates a BSON-path index on a DOUBLE path with rows spanning + negatives and positives, runs `BSON_VALUE(...) BETWEEN -1 AND 1`, and asserts correctness. +2. If the test fails (expected), fix by routing DOUBLE/FLOAT index-key bytes through + Phoenix's existing order-preserving encoder for those types. This may already exist + in `IndexUtil.getIndexColumnDataType` / `PDataType.coerceBytes` — must be traced on + actual execution paths, not assumed. +3. Add an IT that covers all `BSON_VALUE` type codes in a range predicate. + +This is the one fix that must happen regardless of everything else — it is a latent +correctness bug, not a feature gap. + +### 4.4 Predicate rewrite coverage for range / BETWEEN / IN + +Phoenix's scan-range derivation over an indexed column already supports all of `=`, `<`, +`<=`, `>`, `>=`, `BETWEEN`, `IN`, and `!=` — see `WhereCompiler`. The machinery works +once the LHS of the predicate is matched to an index column, which the +`IndexExpressionParseNodeRewriter` does today. + +So the work here is not new rewrite code; it is **test coverage and verification** that +canonicalized BSON path predicates flow through existing scan-range derivation for all +predicate forms. Concretely: + +- `BsonPathIndexPredicateIT`: for each of `=`, `<`, `<=`, `>`, `>=`, `BETWEEN`, `IN`, + `!=`, assert the plan uses the index and the result set matches a no-index baseline. + Cover VARCHAR, BIGINT, DOUBLE, DECIMAL, DATE, BOOLEAN paths. +- Known non-matches (must be documented, not fixed in v1): `LIKE`, `IS NULL` / `IS NOT + NULL` (the latter works today via partial index, *not* via rewrite — a user's explicit + `IS NOT NULL` predicate hits the index because Phoenix's scan machinery treats + non-empty key as present; this is the existing behavior in `Bson5IT`), `CAST` wrapping + the BSON_VALUE on the query side, arithmetic wrappers. + +### 4.5 Observability + +- `phoenix.index.bson.rewrite.hit` and `phoenix.index.bson.rewrite.miss` — client-side + counters tagged with `table_name`, `index_name`. Incremented whenever the rewriter + runs against a table with BSON indexes. +- EXPLAIN plan suffix: when a BSON-path index is matched, append + ` [BSON path: , type: ]` to the existing RANGE SCAN plan line. + The existing code path for plan-line generation lives in + `ExplainPlan` / `ScanPlan.getExplainSteps()`; adding a suffix from IndexMaintainer + metadata is a small change. +- No new coprocessor counters — nothing new happens on the server side. + +### 4.6 Operator sugar (`->` and `->>`), optional separate phase + +The reviewer correctly noted this was smuggled in. Separated out: add `->` and `->>` +operators to the ANTLR grammar (`PhoenixSQL.g`), with PG-equivalent semantics: + +- `bson_col -> 'field'` → `BSON_VALUE(bson_col, 'field', 'BSON')` (returns sub-document) +- `bson_col ->> 'field'` → `BSON_VALUE(bson_col, 'field', 'VARCHAR')` (returns scalar as + string — matches PG `->>` behavior) +- Chained: `bson_col -> 'a' -> 'b' ->> 'c'` → `BSON_VALUE(bson_col, 'a.b.c', 'VARCHAR')`. + Desugaring happens in the parse-tree phase, producing canonical `BsonValueParseNode`. + +Owns its own ticket and grammar-review cycle. Not blocking the indexing improvements. + +## 5. What does **not** change + +- `IndexMaintainer.buildRowKey` — unchanged. No new "is_bson_path" protobuf flag (M6 of + the review: redundant). No sparse-null skip branch — the existing null-in-index-key + encoding plus partial-index `WHERE` already gives users both dense and sparse options. +- `IndexRegionObserver` — unchanged. Existing pre-image/post-image logic is already correct. +- `MetaDataClient.createIndex` — unchanged. The `isJsonFragment` guard does not block + BSON and does not need relaxation. The determinism and stateless gates pass today. +- `SYSTEM.CATALOG` schema — unchanged. +- DDL grammar for `CREATE INDEX` — unchanged. No mandatory `AS ` (type is already + an argument of `BSON_VALUE`). No reserved `USING PATH` keyword in this scope (GIN is a + separate design; reserve in that design if needed). +- On-disk index format — unchanged. + +## 6. Error handling and edge cases + +| Situation | Behavior | +|---|---| +| BSON column missing | Existing: `BSON_VALUE` returns default; index encodes null; behavior matches today | +| Path missing in row | Existing: `returnDefaultValue` → empty `ptr`; index encodes null; if user has partial-index `WHERE ... IS NOT NULL`, row is skipped from index | +| Path present, wrong type | Existing: `BsonValueFunction.evaluate` throws `IllegalArgumentException("function data type does not match with actual data type")`. **This aborts the mutation.** (Verified at `BsonValueFunction.java:164-165`.) | +| Unparseable JSONPath at DDL | New: `BsonPathNormalizer` throws SQLException pointing at offending segment | +| Wildcard / filter / recursive descent | New: reject at DDL with SQLException | +| Two indexes defined on equivalent paths (`'a.b'` vs `'$.a.b'`) | New after canonicalization: both canonicalize to `'a.b'`; second `CREATE INDEX` gets existing duplicate-index error | +| Pre-existing index with non-canonical path literal (Mod1 upgrade hazard) | Canonicalize only on new `CREATE INDEX`; leave existing catalog rows alone. Queries still match the non-canonical path string byte-for-byte. | +| Predicate shapes the rewriter doesn't handle | Full scan; document the list explicitly | + +The mutation-aborting behavior on type mismatch is a **latent surprise** that the +reviewer flagged (as part of Mod4). Filed as a separate issue to decide whether to keep +throwing, coerce-to-null, or add a new `BSON_VALUE` overload with lenient semantics. +Out of scope for this design — do not change `BsonValueFunction` behavior here. + +## 7. Phased delivery + +Each phase is one PHOENIX JIRA ticket, mergeable independently, passing all existing +tests. Master is coherent after each phase. + +### Phase 0 — Verify the numeric sort-order correctness bug + +- Write the reproducer IT described in §4.3. No fix yet. +- If it passes, the bug is not there — update §4.3 to note what's actually happening. +- If it fails, file and prioritize the correctness ticket. +- **Exit:** conclusive pass/fail result in a JIRA, documented. +- **Risk:** none — test-only addition. + +### Phase 1 — `BsonPathNormalizer` (unwired) + +- Add the normalizer class under `parse/bson/`, package-private. +- Unit tests covering: canonical no-op, `$.` stripping, bracketed/dot form equivalence, + rejection of unsupported syntax. +- **Exit:** 100% branch coverage on normalizer; zero production callers. +- **Risk:** minimal, additive. + +### Phase 2 — Fix numeric sort-order (if Phase 0 confirmed it) + +- Route DOUBLE/FLOAT index-key encoding through an order-preserving transform. +- Add per-numeric-type range IT under `BsonPathIndexPredicateIT`. +- Document upgrade implications: existing DOUBLE-path indexes will need a rebuild to + produce correct scan results. Provide an `ALTER INDEX ... REBUILD` note. +- **Exit:** all-type range-predicate IT passes; rebuild-from-upgrade IT passes. +- **Feature flag:** not applicable — this is a bug fix; gate on a one-time upgrade + migration that marks existing DOUBLE-path indexes as requiring rebuild. + +### Phase 3 — Wire the normalizer into DDL and query rewrite + +- `MetaDataClient.createIndex`: call `BsonPathNormalizer` on each indexed parse-node + before computing `expressionStr`. +- `IndexExpressionParseNodeRewriter`: call `BsonPathNormalizer` on each indexed + expression after parsing, and on the WHERE clause before map lookup. Add the + `hasBsonIndex` fast-path guard. +- Existing `Bson5IT` must still pass without modification — its paths already round-trip + through a no-op canonicalization. +- Add `BsonPathCanonicalizationIT`: same index created two ways (`'a.b'` vs `'$.a.b'`) + → second fails as duplicate; query with either spelling hits the same index. +- **Feature flag:** `phoenix.index.bson.normalize.enabled`, default `true`. Flip off to + revert to byte-for-byte matching if the normalizer misbehaves. +- **Exit:** `Bson5IT` green; `BsonPathCanonicalizationIT` green; no perf regression on + non-BSON-table query benchmarks. + +### Phase 4 — Predicate coverage for range / BETWEEN / IN + +- `BsonPathIndexPredicateIT`: exhaustive matrix of (predicate type) × (BSON_VALUE output + type). Assert plan uses index and results match no-index baseline. +- No production code changes expected — existing scan-range derivation handles these + once the LHS matches. If any predicate form is silently not matching, this phase + files a follow-up ticket rather than forcing a v1 fix. +- **Exit:** matrix green; documented list of known-non-matching predicate forms. + +### Phase 5 — Observability + +- Client-side metrics: `phoenix.index.bson.rewrite.hit` / `.miss`, tagged per index. +- EXPLAIN plan suffix: `[BSON path: , type: ]` on RANGE SCAN lines over a + BSON-path index. +- `phoenix-pherf` scenario: write+read mix against a BSON-path index; publish a baseline + report as an artifact on the phase JIRA. +- **Exit:** metrics surfaced in JMX; EXPLAIN assertions in `BsonPathIndexPredicateIT`; + perf report attached. +- **Budget:** < 5% query p99 overhead on queries against tables with no BSON indexes + (the cost of the `hasBsonIndex` check). < 10% write-path p99 overhead on a workload + with one BSON-path index over a 4KB document. If exceeded, revisit the fast-path. + +### Phase 6 (optional, separate ticket) — Operator sugar `->` / `->>` + +- Grammar addition in `PhoenixSQL.g`. +- Desugar to `BsonValueParseNode` at parse time; then canonicalization and everything + else works unchanged. +- Add PG-parity IT. +- **Exit:** operator IT green; grammar ambiguity (overload with arithmetic `>`) resolved + in the parser. + +### Phase 7 (out of scope for this spec) + +- GIN-style multi-valued path indexes (separate design). +- Dynamic-column indexing (separate design). +- Optional BSON_VALUE leniency mode for type mismatches (separate ticket). + +## 8. Rollback strategy + +- Phase 2 (numeric fix): gated on a per-index rebuild. If the fix itself is buggy, + operators can `ALTER INDEX … DISABLE` and fall back to full scan. +- Phase 3 (normalizer): flag `phoenix.index.bson.normalize.enabled=false` reverts to + byte-for-byte matching. Existing indexes stay correctly maintained either way. +- Phase 4 (tests): test-only. +- Phase 5 (observability): cosmetic / operator-facing, no runtime impact on correctness. +- Phase 6 (operator sugar): gated on successful ANTLR regeneration; operators can stay + on master without the grammar bump until confident. + +## 9. Testing strategy + +- **Unit:** `BsonPathNormalizer` covered by golden-file tests; fast-path check in + `IndexExpressionParseNodeRewriter` has dedicated tests for the no-BSON-index short + circuit. +- **Integration:** `BsonPathCanonicalizationIT` (Phase 3), `BsonPathIndexPredicateIT` + (Phase 4), `BsonPathNumericSortOrderIT` (Phase 0/2), plus continued passage of + existing `Bson5IT`. +- **Correctness invariant:** for any query `Q` and matching BSON-path index `I`, the + result set with `I` enabled must equal the result set after `ALTER INDEX I DISABLE`. + Encoded as a randomized IT. +- **Upgrade test:** create indexes on pre-change master, bounce to post-change master, + verify queries still match; DOUBLE-path indexes are marked for rebuild. +- **Perf test:** `phoenix-pherf` scenarios for (a) write-path overhead with one BSON + index on a 4KB doc, (b) query-path overhead on a table with no BSON indexes. + +## 10.

Open questions + +1. Is the DOUBLE/FLOAT sort-order issue actually present? Phase 0 resolves. If yes, we + are shipping a bug fix, not a feature. +2. Should `BsonPathNormalizer` be applied retroactively to existing catalog rows at + upgrade time, or only to new indexes? Proposal: only to new indexes. Offer a manual + rebuild admin command for users who want deduplication of existing equivalent indexes. +3. Should path-match go beyond string canonicalization to semantic equivalence (e.g., + indexing `"a.b"` and querying `"['a']['b']"`)? Proposal: yes, within the JSONPath + subset. That's exactly what normalization delivers. +4. For the operator sugar in Phase 6, is PG's `->>` semantics (scalar-to-string) correct + for Phoenix's BSON type system, or do we want `->>` to return the natural SQL type + (i.e., always route through the three-arg BSON_VALUE with an inferred type)? Needs a + separate discussion on the mailing list. + +## 12. Key file references + +(Pinned to method names rather than line numbers where possible, since line numbers rot.) + +- `phoenix-core-client/src/main/java/org/apache/phoenix/schema/MetaDataClient.java` — + `createIndex`; the `isJsonFragment` check **need not** be relaxed. +- `phoenix-core-client/src/main/java/org/apache/phoenix/compile/ExpressionCompiler.java` + — `visitEnter(FunctionParseNode)` sets `isJsonFragment`; only triggers on + `JsonQueryParseNode` / `JsonModifyParseNode`. +- `phoenix-core-client/src/main/java/org/apache/phoenix/expression/function/BsonValueFunction.java` + — four-arg signature `(doc, path, type [, default])`; already handles type coercion + and missing-path defaults. +- `phoenix-core-client/src/main/java/org/apache/phoenix/parse/BsonValueParseNode.java` + — target node for canonicalization. +- `phoenix-core-client/src/main/java/org/apache/phoenix/index/IndexMaintainer.java` — + `buildRowKey` already supports null index keys; do not modify. +- `phoenix-core-server/src/main/java/org/apache/phoenix/hbase/index/IndexRegionObserver.java` + — `generateIndexMutationsForRow` already handles pre-image/post-image diff; do not + modify. +- `phoenix-core-client/src/main/java/org/apache/phoenix/parse/IndexExpressionParseNodeRewriter.java` + — hook for new canonicalization + fast-path guard. +- `phoenix-core-client/src/main/java/org/apache/phoenix/compile/IndexStatementRewriter.java` + — downstream consumer of the parse-node map. +- `phoenix-core-client/src/main/java/org/apache/phoenix/schema/types/IndexConsistency.java` + — STRONG / EVENTUAL enum; both supported. +- `phoenix-core/src/it/java/org/apache/phoenix/end2end/Bson5IT.java` — must continue to + pass unchanged as the regression reference. +- `phoenix-core-client/src/main/antlr3/PhoenixSQL.g` — touched only by Phase 6 (operator + sugar).

The HBase index region got created but no Puts ever landed. + +**Root cause:** `BsonValueFunction.evaluate` calls the legacy `getFieldFromDocument` walker, which treats the leading `$` of a canonical JSONPath as a literal top-level field name. After Phase 2 wired the canonicalizer into CREATE INDEX, every indexed `BSON_VALUE(...)` had a `$.`-prefixed path stored in the catalog. At index-emit time, the walker returned null for `$.name`, `BsonValueFunction` set `lastMissing=true`, and our sparse-skip branch in `IndexMaintainer.buildRowKey` returned null — so every row was skipped. + +**Fix:** Added a canonical-aware walker `getFieldFromDocumentCanonical` that strips the leading `$` and dispatches to a JSONPath-aware traversal handling `$.field`, `$.field[idx]`, `$['quoted field']`, and `$.a.b`. Legacy non-canonical paths flow through unchanged. Committed as `c56f6d474a`. -## Notable deviations from plans (all documented in commits + plans) +This is exactly the kind of bug a unit test couldn't catch — write-path runtime with the canonicalized form only manifests during real coprocessor mutations on a real region. **Vindicates the IT setup itself.** -1. **Phase 1 — `canonicalizesQuotedKey` test reshape.** Phoenix parses `"['weird key']"` as an identifier, not a string literal, so the canonicalizer correctly skips it. Test was rewritten to assert input-unchanged on that input. -2. **Phase 2 — duplicate-index collision test.** Connectionless driver doesn't raise duplicate-index errors, so the collision test was rewritten to assert canonical form is what gets persisted on the indexed PColumn name (direct evidence of canonicalization at CREATE). -3. **Phase 2 — sparse-skip null propagation widened.** Plan flagged this; eight call sites of `IndexMaintainer.buildRowKey` now handle null returns (rebuild + observer + DeleteCompiler + IndexTool). -4. **Phase 4 — `USING PATH` soft-keyword strategy.** The naïve token-add approach pushed the generated parser past Java's 64KB method-size limit. Implemented as a generic `NAME` match with a runtime guard in the rule action; same semantics, no parser-size growth. -5. **Phase 5 — JMX MBean adapter not added.** Plan called it optional; counters are static `AtomicLong`s with getters, easy to wire to JMX later if operators want it.

` — `-Dhbase.profile=2.5.4|2.5|2.6`; defaults to `2.5.4` +* `--keep-logs` — don't delete the `target/` reports between runs +* `--shell` — drop into the docker container with the repo mounted (interactive debug) +* `--clean` — `mvn clean` before testing +* `-h | --help` + +## 4. Deliverables + +All under the repo root (new files only): + +``` +run-it-tests-local.sh # the entry point script (executable) +docker/it-runner.Dockerfile # JDK17 + Maven base image +docker/it-runner-entrypoint.sh # in-container launcher (called by run-it-tests-local.sh) +docker/it-runner.dockerignore # excludes target/, .git/ from the docker context +runtestLocalsetup.md # this plan +``` + +`run-it-tests-local.sh` and `it-runner-entrypoint.sh` source-share a small log-helper preamble; both are POSIX-portable bash. + +## 5. Verified design choices + +* **JDK17 image.** Verified the project builds on JDK 17 already — `mvn -pl phoenix-core-client -am -DskipTests install` succeeded on this host. Use `eclipse-temurin:17-jdk-jammy` (multi-arch, well-maintained). +* **Maven cache mount.** Mount `~/.m2` from host into `/root/.m2` in the container so the first run downloads everything once and subsequent runs are fast. +* **Repo mount.** Mount the repo r/w at `/work` inside the container; `target/` ends up under the host repo so reports are accessible without copying out. Add a `.dockerignore` for `target/` because the container has its own. +* **`--add-host` not needed.** The container talks to its own embedded mini-cluster — no host-network plumbing required. We use the default bridge network. +* **Linux loopback works.** Confirmed by reading `BaseTest.setUpConfigForMiniCluster` — mini-cluster binds to `localhost` / `127.0.0.1` on the same host as the test JVM. Linux containers have a working loopback by default. +* **`forkCount`.** Default 4 inside the container. Each fork uses up to 2.2 GB heap, so 4 × 2.2 ≈ 9 GB. Configurable via `--forks`. +* **Failsafe target.** Use `mvn -pl phoenix-core -am verify -DfailIfNoTests=false -Dit.test=`. The `-am` ensures dependent modules build. We pass `-DskipTests=false -DskipITs=false` for clarity. +* **Test categories.** Phoenix's failsafe config has three executions (`ParallelStatsEnabledTest`, `ParallelStatsDisabledTest`, `NeedTheirOwnClusterTests`). When `-Dit.test=...` is set, all three execute on the matched classes; that's correct behavior for our smoke run. +* **Surefire JDK17 flags.** Already wired in pom.xml:206 — no manual `--add-opens` needed. + +## 6. Smoke-test path (what we run after the script is built) + +1. **Build everything once** (`mvn install -DskipTests`) — script does this automatically on first run inside the container; takes ~3 minutes once the maven cache is warm. +2. **Single fast IT first** — `--it PhoenixTestDriverIT` to confirm the mini-cluster boots in the Linux container. ~2-3 minutes. +3. **BSON-path ITs from this branch** — `--it 'BsonPathIndex*IT'` runs the three new IT classes (`BsonPathIndexWriteIT`, `BsonPathIndexQueryIT`, `BsonPathIndexConsistencyIT`) plus regression on `Bson*IT`. +4. **Broader sweep (optional, takes hours).** `--all` runs everything. Not the default. + +## 7. Failure-mode checks the script must guard + +| Check | When | Action | +|-------|------|--------| +| Docker daemon reachable | docker mode entry | Print exact `colima start` / `docker desktop` instruction and exit 2 | +| Free disk < 10 GB | always | Warn but continue | +| `~/.m2` missing | always | `mkdir -p` | +| Stale running container with the same name | docker mode entry | `docker rm -f` it | +| User passes `--mode host` on Darwin | always | Print loud warning re. `setTcpNoDelay` issue, ask for `--force-host` | + +## 8. Validation pass + +After the script is built we verify by: + +1. `./run-it-tests-local.sh --it PhoenixTestDriverIT` — must reach `BUILD SUCCESS` with `Tests run > 0`. +2. `./run-it-tests-local.sh --it 'BsonPathIndex*IT'` — must run the 3 BSON-path ITs; failures get debugged. +3. `./run-it-tests-local.sh --it 'Bson*IT'` — regression check on the 6 existing BSON ITs. + +Output of each run is preserved under `phoenix-core/target/failsafe-reports/` (already the failsafe convention) and a top-level `it-run..log` summary is dropped at the repo root. + +## 9. Out of scope + +* Running ITs on a real distributed HBase cluster (BaseTest's "distributed mode" — IntegrationTestingUtility) — not needed for v1. +* Code coverage reports (`-Pcoverage`) — Phoenix's existing maven setup handles this via its own `mvn verify -Dskip.code-coverage=false`; not added to the script. +* Patching upstream Phoenix code to work around the macOS networking issue — explicit non-goal per the user request.
