WAL entry itself is idempotent so replay is not a problem but the intermediate file name and final name when splitting is constructed using the lowest or highest sequence id of the WAL entries written, so it is possible that different WAL files will have same intermediate or final file name when splitting. In the currentm implementation, this will cause split fail or data loss. We need to solve this. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
