------------------------------------
Assignee: Yuchen Liu
> Add option snapshotStartBatchId and snapshotPartitionId to state data source
> ----------------------------------------------------------------------------
>
> Key: SPARK-48589
> URL: https://issues.apache.org/jira/browse/SPARK-48589
> Project: Spark
> Issue Type: New Feature
> Components: Structured Streaming
> Affects Versions: 4.0.0
> Reporter: Yuchen Liu
> Assignee: Yuchen Liu
> Priority: Major
> Labels: pull-request-available
>
> Define two new options, _snapshotStartBatchId_ and _snapshotPartitionId_, for
> the existing state reader. Both of them should be provided at the same time.
> # When there is no snapshot file at that batch (note there is an off-by-one
> issue between version and batch Id), throw an exception.
> # Otherwise, the reader should continue to rebuild the state by reading
> delta files only, and ignore all snapshot files afterwards.
> # Note that if a batchId option is already specified. That batchId is the
> ending batchId, we should then end at that batchId.
