After some discussion we decided not add a new command, instead server and client need to check the capability flags:

  • for servers < 10.2 or MySQL
    • use old format
  • for MariaDB server > 10.2:
    • set iteration_count= 0 for old format (no array binding)
    • set iteration_count to array size for array binding
