[jira] [Created] (RATIS-856) Install Snapshot notifications should be fanned out

Hanisha Koneru created RATIS-856:
------------------------------------

             Summary: Install Snapshot notifications should be fanned out
                 Key: RATIS-856
                 URL: https://issues.apache.org/jira/browse/RATIS-856
             Project: Ratis
          Issue Type: Improvement
            Reporter: Hanisha Koneru
            Assignee: Hanisha Koneru


When InstallSnapshot is disabled and Ratis logs are purged, Leader sends InstallSnapshot notification to Follower. Follower then tells its State Machine to install the snapshot.

 
We should give time for the Follower State Machine to download and install the snapshot. So instead of sending installSnapshot notification for each heartbeat, it would be better if there is a time gap between the sending the notifications.
