I have an existing application that uses Hazelcast for tracking cluster membership and for distributed task execution. I'm thinking that Jet could be useful for adding analytics on top of the existing application, and I'm trying to figure out how best to layer Jet on top of what we already have.
So my first question is, how should run Jet on top of our existing Hazelcast configuration? Do I have to run Jet separately, or replace our existing Hazelcast configuration with Jet (since Jet does expose the HazelcastInstance.)
My second question is, I see lots of examples using IMap and IList, but I'm not seeing anything that uses topics as a source (I also don't see this as an option from the Sources builder). My initial thought on using Jet was to emit events (io perf data, http request data) from our existing code to a topic and then have Jet process that topic, generate analytics from that data, and then push that to an IMap. Is this the wrong approach? Should I be using some other structure to push these events into Jet? I saw that I can make my own custom Source where I could do this, but I felt that I must be going down the wrong path if I was pursuing this given there wasn't one already provided by the library for this specific purpose.
