[jira] [Created] (SPARK-16738) Queryable state for Spark State Store

Mark Sumner created SPARK-16738:
-----------------------------------

             Summary: Queryable state for Spark State Store
                 Key: SPARK-16738
                 URL: https://issues.apache.org/jira/browse/SPARK-16738
             Project: Spark
          Issue Type: New Feature
          Components: Spark Core, SQL, Streaming
    Affects Versions: 2.0.0
            Reporter: Mark Sumner


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.
