[jira] [Created] (RATIS-306) Support multiple storage directories

Tsz Wo Nicholas Sze created RATIS-306:
-----------------------------------------

             Summary: Support multiple storage directories
                 Key: RATIS-306
                 URL: https://issues.apache.org/jira/browse/RATIS-306
             Project: Ratis
          Issue Type: Sub-task
          Components: server
            Reporter: Tsz Wo Nicholas Sze


In the multiple raft group use case, multiple raft logs will be written at the same time.  If there are multiple disk devices available in the server, it is better to have multiple storage directories configured in different disk devices for a better performance.

We may change the server conf {{raft.server.storage.dir}} to take a list of directories so that the server could assign them to individual group.
