[jira] [Created] (HDDS-3191) Interface to write to Ratis before write to SCM DB

Li Cheng created HDDS-3191:
------------------------------

             Summary: Interface to write to Ratis before write to SCM DB
                 Key: HDDS-3191
                 URL: https://issues.apache.org/jira/browse/HDDS-3191
             Project: Hadoop Distributed Data Store
          Issue Type: Sub-task
          Components: SCM
            Reporter: Li Cheng


Due to consistency concern, SCM needs to applyTransaction to RaftLog before it writes to local database and in memory maps. Need refactor the current codes to put this part to Ratis.

Ratis will write to DB on behalf of SCM.
