Motivation
To prevent data corruption from affecting the stability or causing unrecoverable exceptions. Introduce CRC to help validate if the data has corrupted.
Modification
CRC(n) = CRC( DATAn, CRCn-1 )we can validate that followers have exactly the same identical WAL.TxnFormatVersion2for compatibility with the existing format.Others
will add the proposal later.
