Tsz-wo Sze updated RATIS-2134: ------------------------------ Component/s: server > `logMetadata` could miss appending the `metadataEntry` with the > lastCommitIndex > ------------------------------------------------------------------------------- > > Key: RATIS-2134 > URL: https://issues.apache.org/jira/browse/RATIS-2134 > Project: Ratis > Issue Type: Bug > Components: server > Reporter: Chung En Lee > Assignee: Chung En Lee > Priority: Major > Time Spent: 1h 40m > Remaining Estimate: 0h > > Now, RaftLog appends a metadata entry with the lastCommitIndex and checks > whether the entry at the lastCommitIndex is neither a metadata entry nor an > entry with a smaller commit index. > However, RaftLog doesn't always log metadata entries in order. Sometimes, it > misses some commit indexes. For example: > STATEMACHINELOGENTRY(1, 1) > STATEMACHINELOGENTRY(1, 2) > METADATAENTRY(commitIndex: 1) > A {{METADATAENTRY is lost.}} > {{The lastCommitIndex in the METADATAENTRY}} and is a metadata entry, > RaftLog won't append it. -- This message was sent by Atlassian Jira (v8.20.10#820010)
