![]() The suggested pattern for Raft proposals is that they be retried periodically until they succeed. This turns out to be an issue when a leader cannot commit entries because the leader will continue to append re-proposed entries to its log without committing anything. This can result in the uncommitted tail of a leader's log growing without bound until it is able to commit entries. This change add a safeguard to protect against this case where a leader's log can grow without bound during loss of quorum scenarios. It does so by introducing a new, optional ``MaxUncommittedEntriesSize configuration. This config limits the max aggregate size of uncommitted entries that may be appended to a leader's log. Once this limit is exceeded, proposals will begin to return ErrProposalDropped errors. See cockroachdb/cockroach#27772 |
