Hi Johan,
the query is going for a temporary table creation "Using temporary; Using filesort"

In case your sort_buffer_size is too low please try increasing the same. Be cautious don't try to increase it massively, since it is a per thread memory allocation.

please let me know what is your sort_buffer_size by using the command
show global variables like 'sort%';



Regards,
Pradeep Chandru.
