ReplicatedMap
Associates a given value to the specified key and replicates it to the cluster. If there is an old value, it will be replaced by the specified one and returned from the call.
In addition, you have to specify a ttl and its TimeUnit
to define when the value is outdated and thus should be removed from the
replicated map.

ReplicatedMap
The clear operation wipes data out of the replicated maps.
If some node fails on executing the operation, it is retried for at most 5 times (on the failing nodes only).
