    Description

      • Find a way to make MySQL filesort generate temporary files large enough that their content do not fit into IO_CACHE internal buffer and real temp file is created on a disk.
      • Probably extend filesort code with a new DEBUG_SYNC point in order to be able to check temp files content from MTR.
