---------------------------------
    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.
