+:::
+
+![release-0.85](<https://cdn.rilldata.com/docs/release-notes/release-0.85.gif>)
+
+## Snowflake Live Connector
+
+You can now create metrics views directly on Snowflake via the new live connector, expanding Rill's OLAP support beyond ClickHouse and DuckDB.
+
+## Improved First Mile Experience
+
+The onboarding experience has been improved to make getting started with Rill smoother and more guided.
+
+## Preview Mode for Rill Developer
+
+A new Preview Mode lets you preview your dashboards locally before deploying, giving you a faster feedback loop during development.
+
+## Window Support for Glob Partitions
+
+You can now use `start` and `end` to filter glob partitions by path range, making it easy to process only a specific window of data:
+
+```yaml
+#models/s3_model.yaml
+
+#Fixed: Hard-coded start path
+partitions:
+  glob:
+    path: s3://bucket/year=*/month=*/day=*
+    start: s3://bucket/year=2026
+
+# Dynamic: Last 180 entries, i.e. 180 days
+partitions:
+  glob:
+    path: s3://bucket/year=*/month=*/day=*
+    last: 180 
+```
+
+## Cmd+J to Toggle AI Chat
+
+Use `Cmd+J` (or `Ctrl+J`) to quickly toggle the AI chatbot from anywhere in the app.

+title: Snowflake
+description: Power Rill dashboards using Snowflake
+sidebar_label: Snowflake
+sidebar_position: 24
+---
+
+[Snowflake](https://docs.snowflake.com) is a cloud data platform known for its scalability, ease of use, and separation of storage and compute. Rill supports connecting to Snowflake as a live connector, allowing you to build metrics views and dashboards directly on top of existing Snowflake tables — no data movement required.
+
+:::tip Snowflake as a Live Connector vs. Data Source Connector
+Rill supports Snowflake in two distinct modes:
+
+- **OLAP (Live Connector)** — Rill queries Snowflake directly at dashboard load time. No data is ingested into Rill. Use this when your data is already modeled and optimized in Snowflake and you want Rill as a visual layer on top. Set `olap_connector: snowflake` in `rill.yaml`.
+
+- **Data Source Connector** — Rill extracts data from Snowflake and ingests it into its embedded engine (DuckDB or ClickHouse). Use this when you want Rill to manage the data pipeline, apply transformations via SQL models, or combine Snowflake data with other sources. See the [Snowflake data source docs](/developers/build/connectors/data-source/snowflake).
+
+In general, use the live connector if your Snowflake tables are already production-ready and large. Use data source ingestion if you need to transform, join, or enrich the data before building dashboards.
+:::
+
+## Connect to Snowflake
+
+After selecting "Add Data", select Snowflake and fill in your connection parameters. This will automatically create the `snowflake.yaml` file in your `connectors` directory and populate the `.env` file with your credentials.
+
+For more information on supported parameters, see our [Snowflake connector YAML reference docs](/reference/project-files/connectors#snowflake).
+
+```yaml
+type: connector
+driver: snowflake
+
+dsn: "{{ .env.SNOWFLAKE_DSN }}"
+```
+
+:::tip Finding your account identifier
+Your account identifier appears in your Snowflake URL — it's everything before `.snowflakecomputing.com`. For example, if your URL is `https://xy12345.us-east-1.snowflakecomputing.com`, your account identifier is `xy12345.us-east-1`.
+:::
+
+### Key-Pair Authentication (Recommended)
+
+For production use, Snowflake recommends key-pair authentication over passwords. Generate an unencrypted PKCS#8 private key and base64-encode it:
+
+```bash
+# Generate a 2048-bit unencrypted PKCS#8 private key
+openssl genrsa 2048 | openssl pkcs8 -topk8 -nocrypt -out rsa_key.p8
+
+# Base64 URL-encode for use in Rill
+base64 -w 0 rsa_key.p8
+```
+
+Then set the encoded key in your connector:
+
+```yaml
+type: connector
+driver: snowflake
+
+account: "<ACCOUNT_IDENTIFIER>"
+user: "<USERNAME>"
+private_key: "{{ .env.SNOWFLAKE_PRIVATE_KEY }}"
+```
+
+See [Snowflake's key-pair authentication docs](https://docs.snowflake.com/en/guide/key-pair-auth) for full setup instructions.
+
+## Build a Metrics View on Snowflake
+
+Once connected, set Snowflake as the OLAP connector in your `rill.yaml`:
+
+```yaml
+olap_connector: snowflake
+```
+
+Then create a metrics view that references a Snowflake table:
+
+```yaml
+type: metrics_view
+
+connector: snowflake
+database: MY_DATABASE
+database_schema: MY_SCHEMA
+model: MY_TABLE
+
+timeseries: created_at
+dimensions:
+  - column: region
+  - column: category
+measures:
+  - name: total_revenue
+    expression: SUM(revenue)
+```
+
+:::note
+Rill supports metrics views directly on Snowflake as a live connector. Incremental models and partitioned ingestion are not supported in live connector mode.

+### Windowed Glob Partitions
+
+Use `start` and `end` to filter which partitions are processed based on their path — useful for backfills, time-bounded ingestion, or limiting how much data is reprocessed.
+
+- **`start`** — lower bound (inclusive): only partitions with paths ≥ this value are included.
+- **`end`** — upper bound (exclusive): only partitions with paths < this value are included.
+- **`last`** — process only the last N successfully ingested partitions (by lexicographic path order). Useful for rolling windows.
+
+```yaml
+# Fixed window: only process a specific month
+partitions:
+  glob:
+    path: s3://bucket/year=*/month=*/day=*
+    partition: directory
+    start: s3://bucket/year=2026/month=03
+    end: s3://bucket/year=2026/month=04
+sql: SELECT * FROM read_parquet('{{ .partition.uri }}/*.parquet')
+```
+
+```yaml
+# Rolling window: reprocess last 30 days
+partitions:
+  glob:
+    path: s3://bucket/year=*/month=*/day=*
+    partition: directory
+    last: 30
+sql: SELECT * FROM read_parquet('{{ .partition.uri }}/*.parquet')
+```
+
+:::note
+`start`, `end`, and `last` are not compatible with `transform_sql`.
+:::

 ### Viewing Partitions in Rill Developer
 
 Once `partitions:` is defined in your model, a new button will appear in the right-hand panel: `View Partitions`. When selecting this, a new UI will appear with all of your partitions and more information on each. Note that these can be sorted by all, pending, and errors.
