MySQL enforced data integrity checking is disabled¶
Description¶
Enable the slave_sql_verify_checksum causes the replication SQL (applier) thread to verify data using the checksums read from the relay log.
If there’s mismatch, the replica stops with an error.
Setting this variable takes effect for all replication channels immediately, including running channels.
Resolution¶
Set the slave_sql_verify_checksum variable to 1.
For MySQL 8.4 and later: Set the replica_sql_verify_checksum variable to 1. See the MySQL documentation for details.
