Our design is still a bit young, but we're going with a work pulling
pattern right now... which is something that has worked well for me in
the past (this is my first Akka impl though). In terms of the overall
approach of using a queue/datastore effectively as a replacement for a
mailbox (or implementing your own mailbox backed by a data store) it
seems like a valid design to me if you need durable messaging (or just
need messaging across heterogeneous systems). It obviously adds the
communication/serialization overhead to every message, but really any
durable message is going to have the same overhead, so in terms of it
being too heavyweight I don't think I'd worry unless very high
throughput was a real priority. In that case though there are no great
options if you also want the durability... but that is where
distributed data stores or queues can help - if you can scale out your
datastore and consumers then you can get throughput even on durable
messages.
I wouldn't be surprised if there were also some good options using
Akka alone. On top of my large queue concerns with Rabbit I didn't
particularly feel like adding another component into the mix if I
didn't need to. I wouldn't be shocked if you could do something pretty
cleanly with just akka persistence. I haven't looked into the new akka
streams but that provides some pretty nice looking flow control you
might be able to use.
You may be interested in this pull request
<https://github.com/akka/akka/pull/15036> that enables reading from
akka-persistence journals via reactive-stream producers.
I'd be interested to hear some Akka-oriented options from the crew out
there.
