Did you test out ARDB [1] when you chose SSDB? I've been considering these for a while since I know I'm going to hit that choice point though that's not happened yet.
Looked at it, but setup for SSDB was easier and already was using SSDB in production. Hesitant to change something that's working so well. Do have periodic connection issues with SSDB but so infrequent it's easy to work around client-side. Using the python redis [1] client with Flask.
