innodb_checksum_algorithm

Overview

In 10.6 ES, 10.6 CS:

The algorithm InnoDB uses for page checksumming. Possible values are FULL_CRC32 for new files, always use CRC-32C; for old, see CRC32 below; STRICT_FULL_CRC32 for new files, always use CRC-32C; for old, see STRICT_CRC32 below; CRC32 write crc32, allow any of the other checksums to match when reading; STRICT_CRC32 write crc32, do not allow other algorithms to match when reading; INNODB write a software calculated checksum, allow any other checksums to match when reading; STRICT_INNODB write a software calculated checksum, do not allow other algorithms to match when reading; NONE write a constant magic number, do not do any checksum verification when reading; STRICT_NONE write a constant magic number, do not allow values other than that magic number when reading; Files updated when this option is set to crc32 or strict_crc32 will not be readable by MariaDB versions older than 10.0.4; new files created with full_crc32 are readable by MariaDB 10.4.3+

In 10.6 ES:

The algorithm InnoDB uses for page checksumming. Possible values are FULL_CRC32 for new files, always use CRC-32C; for old, see CRC32 below; STRICT_FULL_CRC32 for new files, always use CRC-32C; for old, see STRICT_CRC32 below; CRC32 write crc32, allow any of the other checksums to match when reading; STRICT_CRC32 write crc32, do not allow other algorithms to match when reading; INNODB write a software calculated checksum, allow any other checksums to match when reading; STRICT_INNODB write a software calculated checksum, do not allow other algorithms to match when reading; NONE write a constant magic number, do not do any checksum verification when reading; STRICT_NONE write a constant magic number, do not allow values other than that magic number when reading; Files updated when this option is set to crc32 or strict_crc32 will not be readable by MariaDB versions older than 10.0.4; new files created with full_crc32 are readable by MariaDB 10.4.3+

In 10.5 ES, 10.5 CS, 10.4 ES, 10.4 CS:

The algorithm InnoDB uses for page checksumming. Possible values are FULL_CRC32 for new files, always use CRC-32C; for old, see CRC32 below; STRICT_FULL_CRC32 for new files, always use CRC-32C; for old, see STRICT_CRC32 below; CRC32 write crc32, allow any of the other checksums to match when reading; STRICT_CRC32 write crc32, do not allow other algorithms to match when reading; INNODB write a software calculated checksum, allow any other checksums to match when reading; STRICT_INNODB write a software calculated checksum, do not allow other algorithms to match when reading; NONE write a constant magic number, do not do any checksum verification when reading (same as innodb_checksums=OFF); STRICT_NONE write a constant magic number, do not allow values other than that magic number when reading; Files updated when this option is set to crc32 or strict_crc32 will not be readable by MariaDB versions older than 10.0.4; new files created with full_crc32 are readable by MariaDB 10.4.3+

In 10.5 ES, 10.4 ES:

The algorithm InnoDB uses for page checksumming. Possible values are FULL_CRC32 for new files, always use CRC-32C; for old, see CRC32 below; STRICT_FULL_CRC32 for new files, always use CRC-32C; for old, see STRICT_CRC32 below; CRC32 write crc32, allow any of the other checksums to match when reading; STRICT_CRC32 write crc32, do not allow other algorithms to match when reading; INNODB write a software calculated checksum, allow any other checksums to match when reading; STRICT_INNODB write a software calculated checksum, do not allow other algorithms to match when reading; NONE write a constant magic number, do not do any checksum verification when reading (same as innodb_checksums=OFF); STRICT_NONE write a constant magic number, do not allow values other than that magic number when reading; Files updated when this option is set to crc32 or strict_crc32 will not be readable by MariaDB versions older than 10.0.4; new files created with full_crc32 are readable by MariaDB 10.4.3+

In 10.3 ES, 10.3 CS, 10.2 ES, 10.2 CS:

The algorithm InnoDB uses for page checksumming. Possible values are CRC32 (hardware accelerated if the CPU supports it) write crc32, allow any of the other checksums to match when reading; STRICT_CRC32 write crc32, do not allow other algorithms to match when reading; INNODB write a software calculated checksum, allow any other checksums to match when reading; STRICT_INNODB write a software calculated checksum, do not allow other algorithms to match when reading; NONE write a constant magic number, do not do any checksum verification when reading (same as innodb_checksums=OFF); STRICT_NONE write a constant magic number, do not allow values other than that magic number when reading; Files updated when this option is set to crc32 or strict_crc32 will not be readable by MariaDB versions older than 10.0.4
