@olivergeorge I'm not sure about workers in react native, but you're probably right about the serialization cost. If you find a nice abstraction for querying into a db in a worker then that would be very cool, but then you'd still have problems with (de)serializing if your transactions/query results are large.
Cool to hear what you came up with by the way. How are you liking react native?
I would imagine transit could be quite useful when communicating across workers
