> Add SequentialUnionManager to manage source activation
> -------------------------------------------------------
>
> Key: SPARK-55477
> URL: https://issues.apache.org/jira/browse/SPARK-55477
> Project: Spark
> Issue Type: Task
> Components: Structured Streaming
> Affects Versions: 4.2.0
> Reporter: Eric Marnadi
> Priority: Major
>
> Add SequentialUnionManager, which manages state and lifecycle for
> SequentialStreamingUnion nodes during streaming execution. The manager:
> * Tracks which source is currently active in a sequential union
> * Manages transitions between sources when exhaustion is detected
> * Handles just-in-time preparation of sources with AvailableNow semantics
> * Provides serializable offset representation for checkpoint recovery
