> Unload State Store Provider after configured keep alive time
> ------------------------------------------------------------

> Key: SPARK-33783

> Project: Spark
> Issue Type: New Feature
> Components: Structured Streaming
> Affects Versions: 3.2.0
> Reporter: L. C. Hsieh

> Currently Spark unloads an inactive state store provider in an maintenance
> task which is run periodically. So it is said one state store provider might
> be unloaded immediately after it becomes inactive because the maintenance
> task is asynchronous. It is inefficient as the state store provider could be
> reused in next batches and we should be able to have more control of
> unloading behavior.
