-------------------------------------
Assignee: L. C. Hsieh
> Add additional checkpoint rename file check
> -------------------------------------------
>
> Key: SPARK-40826
> URL: https://issues.apache.org/jira/browse/SPARK-40826
> Project: Spark
> Issue Type: Improvement
> Components: Structured Streaming
> Affects Versions: 3.4.0
> Reporter: L. C. Hsieh
> Assignee: L. C. Hsieh
> Priority: Major
>
> We encountered an issue recently that one customer's structured streaming job
> failed to read delta file.
> The temporary file exists but it was not successfully renamed to final delta
> file path.
> We currently don't check if renamed file exists but assume it successful. As
> the result, failing to read delta file assumed to be committed in last batch
> makes re-triggering the job impossible.
> We should be able to do a check against checkpoint renamed file to prevent
> such difficulty in advance.
