Apache Spark reassigned SPARK-36619:
------------------------------------
Assignee: Apache Spark
> Iterators on prefix scan in RocksDB are not cleaned up unless aborting
> ----------------------------------------------------------------------
>
> Key: SPARK-36619
> URL: https://issues.apache.org/jira/browse/SPARK-36619
> Project: Spark
> Issue Type: Bug
> Components: Structured Streaming
> Affects Versions: 3.2.0
> Reporter: Jungtaek Lim
> Assignee: Apache Spark
> Priority: Blocker
>
> In RocksDB state store provider implementation, we leverage iterators on
> prefix scan, which are being closed in rollback() method.
> While this works now for session window since state store instance in read
> physical plan will always call abort, it could bring correctness issue for
> stateful operator which doesn't instantiate two different physical plans on
> read and write.
> We should make sure these iterators get closed to let these iterators don't
> affect multiple micro-batches (plays as side-effect).
