Is Hazelcast Client thread safe?

Question

I cannot find this in the docs or javadocs: do I need to create one client per thread or is a client created by:

client = HazelcastClient.newHazelcastClient(cfg);

thread safe?

Answer 1

The client is thread-safe. Also when you get e.g. an IMap from it, it also is thread-safe.

HazelcastInstance client = HazelcastClient.newHazelcastClient(cfg)
IMap map = client.getMap("map");

So you can share this client instance with all your threads in the JVM.
