This looks interesting! Currently, we have a huge background processing system built using Sidekiq backed by Redis. The biggest problem we are facing today is to run machines with lot of in-memory storage because jobs are queued to Redis and Redis works in-memory. These machines costs a lot. I think the same issue will happen even here because this is also in-memory store and persistence works like how Redis handles it.
