ORDER BY / GROYP BY slow - MySQL 8.0
Posted by: Christos Chatzaras

I use query https://dpaste.com/EFQYBCQYG with MySQL 8.0 which takes 1.2 sec.

If I remove ORDER BY and GROUP BY then it takes 0.0087 sec.

I guess the slowdown is because of filesort.

Can I use an index to speedup it? Or any my.cnf configuration?
