Hazelcast working at mutlinode

Question

In mutinode they say N1, N2 and N3. I immediately got to node N1, but what is happening is that for some reason LELEVAK communicates with N2 and N3. This is not a heart test, as it is set for 1 minute. But I watched using wirehark , it clearly shows that the call goes to another node (i.e.) from N1 to N2.

This clearly shows that when I push a request to N1, this request is passed to N2. I saw the request and the data received in wirehark.

I am rather confused why this is happening. All data should be there in node 1, but why will it move to another node to retrieve the data?

Thanks Harry

Answer 1

The data in Hazelcast is divided, so it doesn’t matter which node to add data to, there is no guarantee that the record will be saved on this node. This means that there is a connection to store / read data in a partitioned way. You will probably want to read the data section: http://docs.hazelcast.org/docs/3.6/manual/html-single/index.html#data-partitioning
