Regretfully, the parameter innodb_log_checksums was introduced in MySQL 5.7.9 (the first GA release of that series) by mysql/mysql-server@af0acedd88 which partly replaced a parameter that had been introduced in 5.7.8 mysql/mysql-server@22ba38218e as innodb_log_checksum_algorithm. Given that the CRC-32C operations are accelerated on many processor implementations (AMD64 with SSE4.2; since MDEV-22669 also on IA-32 with SSE4.2, POWER 8 and later, ARMv8 with some extensions) and by lookup tables when only generic SISD instructions are available, there should be no valid reason to disable checksums. In MariaDB 10.5.2, as a preparation for MDEV-12353, MDEV-19543 deprecated and ignored the parameter innodb_log_checksums altogether. This should imply that after a clean shutdown with innodb_log_checksums=OFF one cannot upgrade to MariaDB Server 10.5 at all. Due to these problems, let us deprecate the parameter innodb_log_checksums and honor it only during server startup. The command SET GLOBAL innodb_log_checksums will always set the parameter to ON. |
