Hi @kl0u ,
Thanks for addressing my comments. I've made some new ones :) but looks
much better.
As for merging the different types of snapshots, the only solution I see
now, is to let all the accumulator results go through the BlobCache. That might
cause some extra latency at the end of the job. I'm not sure whether we should
proceed on that path but the current solution has a lot of added overhead
because we need to deal with two different kind of update mechanisms.
I would like to hear some other opinions on whether we should have both
update mechanisms (BlobCache and Akka message-based) or just let everything go
through the BlobCache. I'm leaning more towards the latter if it is not too
slow for slow accumulators.
I think you have to rebase to the latest master again because of some minor
changes.
