Tsz Wo Nicholas Sze updated RATIS-352: -------------------------------------- Attachment: r352_20181022.patch > Persist commit index in Raft log. > --------------------------------- > > Key: RATIS-352 > URL: https://issues.apache.org/jira/browse/RATIS-352 > Project: Ratis > Issue Type: Improvement > Components: server > Reporter: Tsz Wo Nicholas Sze > Assignee: Tsz Wo Nicholas Sze > Priority: Major > Attachments: r352_20181022.patch > > > Current the commit index is not persisted in the Raft log. When a server > restarts, it cannot apply its log until it has joined a Raft group. There is > no problem if there is a Raft group. > However, a server cannot recover its data when formatting a Raft group is > impossible (e.g. a majority of servers are dead). Ideally, a server can > safely apply the log up to the commit index. The JIRA is to persist the > commit index so that such recovery is possible. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
