---------------------------------------------

@[~hyukjin.kwon] I think this should target a future version. I have asked the list if we agree to start working on it but got no feedback.

>          Components: Structured Streaming
>    Affects Versions: 2.0.0

> Spark 2.0 will introduce the new State Store to allow state managment outside the RDD model (see: SPARK-13809)
> This proposal seeks to include a mechanism (in a future release) to expose this internal store to external applications for querying.
> This would then make it possible to interact with aggregated state without needing to synchronously write (and read) to/from an external store.
