public SharedData getSharedData(String name)

Description copied from interface: SharedDataManager

Obtain a SharedDataManager for the given key. Data managed via that provider will be shared across all nodes of the cluster.

The returned shared data provider makes no consistency guarantees. On a single node cluster, or in a non-clustered installation, strong consistency can be assumed, and in a multi-node cluster a best-effort consistency will be provided. Some implementations may provide strong consistency, others may only provide weak and/or eventual consistency.

The shared data should be persistent as long as at least one node of the cluster remains running. If multiple cluster nodes fail simultaneously, then the data may be lost. Implementations may persist this data even if the whole cluster is restarted, but clients should not assume one way or the other.
