HazelCast support for Observer Pattern.

[Ram]

I have a use case where I have to do very large chained computations with no prior information about how long the chains are. Using mechanisms like Queues, Pub/Sub etc do not scale as well as do not give the sub second time completion. 

So what I am looking for is, whether HazelCast supports the Observer Pattern the way Java has Observer Interface and Observable Class using which we can create a event generation and propagation mechanism that is fast.

I saw that there is JCache support. Does this exactly replace the Observer pattern with its event structure?

Hi Ram,

you can register an entry listener which will be fired when there is a change. Is that what you are asking? You can also have a look at the Hazelcast RxJava integration. 

If you application is doing heavy computations then you might want to have a look at Hazelcast Jet - it's our new project focused specifically on distributed computing and stream processing. 

Cheers,
