Returns a lazy
Set view of the mappings contained in this map.A LazySet is optimized for querying speed (preventing eager deserialization and hashing on HashSet insertion) and does NOT provide all operations. |

Returns the key of the partition that this DistributedObject is assigned to.

ReplicatedMapAssociates 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to define when the value is outdated and thus should be removed from the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.

ReplicatedMapThe 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).

ReplicatedMapSet view of the key contained in this map.UnsupportedOperationException. Same is true for operations
like Set.contains(Object) and

very poor performance if called repeatedly (for example, in a loop). If the use
case is different from querying the data, please copy the resulting set into a
new HashSet.
