[jira] [Assigned] (SPARK-32555) Add unique ID on QueryExecution to
enable listeners to deduplicate

> -------------------------------------------------------------------
>
> Key: SPARK-32555
> URL: https://issues.apache.org/jira/browse/SPARK-32555
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.1.0
> Reporter: Jungtaek Lim
> Priority: Minor
>
> Somehow there's a change Spark calls QueryExecutionListener multiple times on same QueryExecution instance (even same funcName for onSuccess).
> There's no unique ID on QueryExecution, hence it's a bit tricky if the listener would like to deal with same query execution only once.
> This issue tracks the effort on adding unique ID on QueryExecution, so that listener can leverage the ID to deduplicate callbacks.
