Hi Folks,
We are using MySQL 5.7 in prod. I setup a MySQL 8.0.26-17 slave for one of the masters to evaluate it.
I saw it was consuming lot more CPU than other 5.7 slaves of the same master.
Linux perf tool showed it is spending lot of time in show_slave_status_cmd.
I changed to use “show replica status” and CPU usage of 8.0 slave dropped a lot.
Is this a bug? Has anyone else seen this? One would think “show replica status” is just an alias for “show slave status”?
Thanks,
Vamsi
