Hi, 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, Igor -- View this message in context: http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/Usecase-for-Flink-tp4076.html Sent from the Apache Flink User Mailing List archive. mailing list archive at Nabble.com.
