hi guys, today I'm working on SQLAlchemy/oslo.db pooling and I started to wonder for how long we should keep inactive mysql connections(a.k.a wait_timeout/connection_recycle_time).
By default it's: 8h for mariadb upstream(1h in our galera_server role) and 1h for oslo.db pooling. Both of these values seem to be a lot too high for me.
Do You have anything against setting it to 1 minute by default?
I'm trying to reduce sleeping SQL connections because currently, if galera node dies, they won't be dropped until this timeout and max_connections limit may be exceeded
