Labels: pull-request-available (was: )
> Move streamingSourceIdentifyingName from CatalogTable to DataSource
> -------------------------------------------------------------------
>
> Key: SPARK-55402
> URL: https://issues.apache.org/jira/browse/SPARK-55402
> Project: Spark
> Issue Type: Task
> Components: Structured Streaming
> Affects Versions: 4.2.0
> Reporter: Eric Marnadi
> Priority: Major
> Labels: pull-request-available
>
> streamingSourceIdentifyingName represents query-specific metadata (which
> source name was assigned in a particular streaming query plan), not an
> intrinsic property of the table itself. Storing it in CatalogTable breaks
> table equality semantics:
> - Two references to the same table in a single query can have different
> streamingSourceIdentifyingName values
> - This causes them to compare as unequal via CatalogTable.equals()
> - This can impact multi-statement transactions and any caching/deduplication
> logic that relies on CatalogTable equality. By moving this field to
> DataSource (which is already query-specific), we restore proper catalog table
> equality while maintaining the ability to track streaming source identifying
> names for stable checkpoints.
