    • Q2/2026 Server Maintenance, Q2/2026 Server Development

    Description

      MDEV-9826 adds some xxh use in the server, now we can add an sql function, same as md5 and others

      After discussion with the team (bar,serg,ycp), we decided to go with the following function signatures:

      XXH32(expr) --> INT UNSIGNED
      		 
      XXH3(expr) --> BIGINT UNSIGNED
      		 
      XXH64(expr) --> BIGINT UNSIGNED (will be done in a spearate task)
      		 
      XXH128(expr) --> BINARY(16)    (will be done in a separate task)
