TODO: Reconcile these values when scalers share pools but present different connection pool settings
- select max/min/etc
- OR create new connection and add to pool

I think that maybe we could hide this parameter for the moment and share them if there is any request from users. As they can have different values, this could be so difficult to debug.

Hey, yeah, just to clarify, did you mean to remove all the new parameters, thus making the globally shared connection pools the default, or just the connection pool tuning parameters?
I also thought a MySQL scaler v2 might fit as well for this, if that's of interest at all?

I'm not sure if adding a v2 scaler makes sense as we could potentially implement a connection pool as part of #6360.
Definitivelly, supporting this in mysql/postgre scalers is worth, but adding v2 scaler to include this feature could be an overkill as it won't make sense if we address a global connection pool

Sure, was just a musing thought, and I lean on your thoughts here as you know the project much better than I
I was exploring how I might even end to end test this so I'll poke at that a bit more then move it out of draft when its all done. I'm also not entirely convinced by the global scope of the connection pool cache.
