I have a MySQL RDS instance that's got 100+ queries all stuck waiting for a table metadata lock.
The good news
I have permission to kill all of the sessions, and have 0 concern for data loss as this database is completely reloaded as needed.
The bad news
It's a MySQL instance running as a hosted RDS instance in AWS AND while I have access to the "root" MySQL account, I don't have access to the AWS console that this RDS instance is hosted in.
What I've tried
When this has happened previously, I look through the connections and run
CALL mysql.rds_kill(_each_and_every_process_id_one_at_a_time). However, this time, when I try run one of these kill statements, it simply hangs. (I'm doing this through MySQL workbench)
What options do I have? Is there someway to "escalate" my
mysql.rds_kill call so that it's handled right away? Do I try executing this outside of workbench somehow?
