performance_schema not to use md5 for digest

    XMLWordPrintable

Details

    Description

      Currently the performance schema uses md5 digests.

      A SHA256 hash is more modern and while the use doesn't require cryptographic security, its an easy enough change MySQL implementation.

      XXH3, added to MariaDB in MDEV-9826, Is being implemented as a much faster algorithm.

      Please note that the MariaDB PS DIGEST feature is not a security feature and is not meant to be used as such.
      MariaDB's current implementation is purely for query identification in statistics, not database activity monitoring etc.
      As such, a fast hashing algo like XXH3 is a significantly better choice than the slow SHA256.
      More generally, XXH3 is not a secure hash, and it should not be used for security purposes.
