How have you had so many issues with Redis. We used it at a previous place it was basically bullet proof. That being said we didn’t use Java but Python. Idk.

lettuce - doesn't reconnect properly during redis restarts (1/10 chance) jedis - subscriptions drop and stop receiving for no reason

however, my latest wrapper for jedis does seem to be holding up and haven't had too many issues, but I have a very robust checking for dropped connections.
