Add an EXISTS command #161

Closed k4nar closed 10 years ago

k4nar commented 10 years ago

I think an EXISTS command would be very useful. Plyvel doesn't handle it out-of-the box, but it can be implemented quite simply using this tip. The main point is to avoid getting the value of the key.

Okay, let's add an EXISTS command. I'll add it to the specification for latest versions and, this integration will be considered as a backport.

Working on it.
