Correct usage of the destroy() method

[Luis Fernando Planella Gonzalez]

Hi.
I've been using the .destroy() method on created IMaps and ITopics.
However, I'm now in doubt if I really have to do it or not, as the
examples on the docs don't state that clearly.
Should I invoke the destroy() method on maps, topics, locks, etc? Or
is the Hazelcast.getLifecycleService().shutdown() enough to release
all resources?
Thanks.

Destruction of map or topic releases resources related to that map or topic across the cluster, in all nodes. If you won't use a map or a topic anymore, then you can call destroy safely. But HazelcastInstance shutdown releases all resources allocated in current node, not in the whole cluster. To release resources of single node, it's enough to call HazelcastInstance shutdown.

Ouch. I was assuming I had to call destroy on each node shutdown.
Thanks!
