Xuannan Su created FLINK-13570:
----------------------------------

             Summary: Pluggable Intermediate Result Storage
                 Key: FLINK-13570
                 URL: https://issues.apache.org/jira/browse/FLINK-13570
             Project: Flink
          Issue Type: New Feature
          Components: Table SQL / API
            Reporter: Xuannan Su


As discussed in [FLIP-48|https://cwiki.apache.org/confluence/display/FLINK/FLIP-48%3A+Pluggable+Intermediate+Result+Storage], the intermediate result storage is the backend storage where the content of the cached table stored.

[FLIP-36|https://cwiki.apache.org/confluence/display/FLINK/FLIP-36%3A+Support+Interactive+Programming+in+Flink] provides a default implementation of the intermediate result storage so that the user can use the cache out of the box. 

For more advanced usage of the cache, users may want to plug in some external storages to store the intermediate result. This task is to provide the necessary interfaces for the pluggable intermediate result storage and implementation of using the filesystem as the intermediate result storage.
