> ---------------------------------------------------------------------
>
> Key: SPARK-40492
> URL: https://issues.apache.org/jira/browse/SPARK-40492
> Project: Spark
> Issue Type: Bug
> Components: Structured Streaming
> Affects Versions: 3.3.0
> Reporter: Chaoqin Li
> Assignee: Apache Spark
> Priority: Major
>
> Current the maintenance of StateStore is performed by a periodic task in the
> management thread. If a streaming query become inactive before the next
> maintenance task fire, its StateStore will be unloaded before cleanup.
> There are 2 cases when a StateStore is unloaded.
> # StateStoreProvider is not longer active in the system, for example, when a
> query ends or the spark context terminates.
> # There is other active StateStoreProvider in the system, for example, when
> a partition is reassigned.
> In case 1, we should do one last maintenance before unloading the instance.
