How to disable automatic key creation in ZINCRBY?

Hi, I’m looking to use ZINCRBY to change the state of a leaderboard, but without creating a new key because that would add a new key that should have expired. How do I do this? Thank you for your help!

There is no atomic way to do ZINCRBY only when it exists (as with SET with the XX flag). So your best bet is to do an EXISTS and only run ZINCRBY if it returns a nonzero value.
