Examples of ReplicatedMap

com.hazelcast.core.ReplicatedMap

A ReplicatedMap is a map like data structure with non-strong consistency (so-called eventually consistent) and values are locally stored on every node of the cluster. When accessing values, due to the eventually consistency, it is possible to read staled data since replication is not handled in a synchronous way.

Whenever a value is written asynchronously the new value will be internally distributed to all existing cluster members and eventually every node will have the new value and the cluster again is in a consistent state.

When a new node joins the cluster the new node initially will request existing values from older nodes and replicate those locally.

All-to-all replication for a hash map implementation. Each node in the cluster will carry an identical copy of the map.

This map implementation doesn't have a background thread running to replicate changes. If you do have changes without invoking put/remove then you need to invoke one of the following methods:
- replicate(Object,boolean) - replicates only the object that belongs to the key
- replicate(boolean) - Scans the entire map for changes and replicates data
the boolean value in the replicate method used to decide whether to only replicate objects that implement the ReplicatedMapEntry interface or to replicate all objects. If an object doesn't implement the ReplicatedMapEntry interface each time the object gets replicated the entire object gets serialized, hence a call to replicate(true) will replicate all objects in this map that are using this node as primary.

REMEMBER TO CALL breakdown() or finalize() when you are done with the map to avoid memory leaks.
