Subject Usecase for Flink
Date Thu, 17 Dec 2015 07:54:25 GMT
We are looking at Flink and trying to understand if our usecase is relevant
to it.

We need process stream of events. Each event is for some id(e.g. device id),
when each event should be 
1. stored in some persistent storage(e.g. cassandra)
2. previously persisted events should be fetched and some computation over
whole history may or may not trigger some other events(e.g. sending email)

so yes we have stream of events, but we need persistent store(aka external
service) in the middle
and there is no aggregation of those events into something smaller which
could be stored in memory, i.e. number of ids might be huge and previous
history of events per each id can be considerable so that no way to store
everything in memory

I was wondering if akka stream is sort of optional solution too

please share your ideas :)
thanks in advance,
