Does get(replicated)map load the whole data or just the reference?

Question

I would like to get the value of a key, however the Map is large so I don't want it to be completely loaded into memory. So if I do something like:

hazelcast.getReplicatedMap(name).get(key)

will it load the whole map into memory then get the value?

If yes, is there a way to get the value of a key without loading everything into memory?

Answer 1

EDIT: Please see @pveentjer's answer since I supposed the question was asked for client topology and answered accordingly.

It does not load the whole map but returns an instance of it. So when you call hazelcast.getReplicatedMap(name).get(key) only one entry - if exists, will be fetched from distributed map.
