>          Components: Structured Streaming
>    Affects Versions: 4.2.0

> With SPARK-55144, the state format of the primary store would support for 
> "prefix scan + range scan on event time". That allows us to perform the 
> retrieval operation of time interval join more efficiently, via only scanning 
> through the timestamp range which is constructed with "time interval 
> condition".
> This ticket tracks the effort of modifying the state store API and state 
> manager, and modifying stream-stream join operator to integrate the change.
