DEPS: bump sqlalchemy min support version to 1.4.0
precursor of #42976

no this is fine
the prior version is for compatibility (i mean if we can keep 1.3.11 compat would be great but not sure it's possible) hah I didn't realize this was just a dep bump, ok. @fangchenli if we wanted to have pre 1.4 compat (as well); how hard would this be? > @fangchenli if we wanted to have pre 1.4 compat (as well); how hard would this be?

pre 1.4 sqlalchemy freezes the CI in #42976. We could delay the refactoring of SQL tests to keep the pre 1.4 compact. I think we might even have sqlalchemy 1.4 compat problems see #40682. This might not be safe to do for 1.4. This pull request is stale because it has been open for thirty days with no activity. Please update or respond to this comment if you're still interested in working on this. > I think we might even have sqlalchemy 1.4 compat problems see #40682. This might not be safe to do for 1.4.

@lithomas1 can you clarify are you saying this isn't safe to do for pandas 1.4 or isnt safe to support sqlalchemy 1.4? I meant bumping the min version for pandas 1.4.0. Sorry for the confusion @fangchenli status of this? > @fangchenli status of this?

ready can you add a whatsnew note about this change (assume we are dropping < 1.4)? (fine by me) > can you add a whatsnew note about this change (assume we are dropping < 1.4)? (fine by me)

It's already included in the 1.4 whatsnew doc. thanks @fangchenli
