@tonyxuqqi What is the WAL recovery mode in tikv ? I guess that it should be kTolerateCorruptedTailRecords.

which format is tikv using. Seems like rocksdb wal has two formats : legacy and recycle. Recycle format has more debug information (log number) . https://github.com/facebook/rocksdb/wiki/Write-Ahead-Log-File-Format
