    Description

      table with primery key binary(16)

      `SELECT from table WHERE key IN (binary form ids, ....)` is extremly slow

      while

      `SELECT from table WHERE key IN ((0x11e6a2ad166fc342abde002590a2360a),
      (0x11e6a2ad16750370aeaf002590a2360a),
      (0x11e6a2ad167a186a9e19002590a2360a),....)`
      is perfectly fast.

      IDs in binary form I mean this: https://tinyurl.com/ycfyftby
