L. C. Hsieh resolved SPARK-34321.
---------------------------------
Resolution: Invalid
> Fix the guarantee of foreachBatch
> ---------------------------------
>
> Key: SPARK-34321
> URL: https://issues.apache.org/jira/browse/SPARK-34321
> Project: Spark
> Issue Type: Documentation
> Components: Structured Streaming
> Affects Versions: 3.2.0
> Reporter: L. C. Hsieh
> Assignee: L. C. Hsieh
> Priority: Major
>
> Similar to SPARK-28650, {{foreachBatch}} API document also documents the
> guarantee:
> The batchId can be used to deduplicate and transactionally write the output
> (that is, the provided Dataset) to external systems. The output Dataset is
> guaranteed to be exactly the same for the same batchId
> But like the reason of fixing the document of {{ForeachWriter}} in
> SPARK-28650, it is not hard to break the guarantee by changing the partition
> number.
