------------------------------------------
Assignee: Eric Marnadi
> Introduce NamedStreamingRelation wrapper for source identification during
> analysis
> -----------------------------------------------------------------------------------
>
> Key: SPARK-54867
> URL: https://issues.apache.org/jira/browse/SPARK-54867
> Project: Spark
> Issue Type: Improvement
> Components: Structured Streaming
> Affects Versions: 4.2.0
> Reporter: Eric Marnadi
> Assignee: Eric Marnadi
> Priority: Major
> Labels: pull-request-available
>
> Streaming sources need stable, predictable names for:
> - Checkpoint location stability - Schema evolution and offset tracking
> require consistent source identification
> - Schema lookup at specific offsets - Analysis-time operations need to
> reference sources by name
> - Flow integration - DLT and similar systems need per-source metadata paths
> - User control - Allow users to explicitly name sources via the `.name()` API
> By introducing this wrapper during analysis (rather than at execution
> planning), we enable these capabilities while maintaining a clean separation
> between parsing, analysis, and execution phases.
