@PragmaTwice What would be most ideal for handling expiring keys, lazy expiration, active expiration, etc.?

jonathanc-n commented 6 days ago

I think I will go with a lazy expiration strategy. Probably a combination of that, and a background thread that will clear keys. Btw, do you know how to access ttl keys?
