When Leader does not have the logs to get > the Follower up to speed, it should notify the Follower to install a snapshot > (if install snapshot through Log Appender is disabled). The Follower in turn > notifies its state machine that a snapshot is required to catch up with the > leader. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
