Re: query with bad performance after migration to mysql 5.6

Hi,

The provided optimizer trace is not complete. When the MISSING_BYTES_BEYOND_MAX_MEM_SIZE column of the optimizer_trace table is non-zero, it means that the allocated buffer was to small for the entire trace. To increase the buffer size, change the setting of optimizer_trace_max_mem_size variable.

Thanks,
