 The transferTag is used by clients to label transfers with activity-specific information, such as experiment ID and workflow ID. This information is currently provided by XRootD and HTTP clients, and can be used by monitoring systems to identify data flows.

 A Kafka producer operates asynchronously by default: when an application calls send(), the record is placed into an internal buffer and the call typically returns immediately, without waiting for broker acknowledgements.
 
 However, asynchronous operation does not guarantee fully non-blocking behavior. Under certain conditions—such as broker unavailability, missing topic metadata, or exhausted producer buffers—the producer may block or fail synchronously. These edge cases are a common source of confusion and can lead to unexpected application failures.
