Interface ClusterInfo

All Known Implementing Classes:

public interface ClusterInfo
Provides information about a Cluster. Selected bucket properties are available through explicit getters, the full (raw JSON) response from the server is accessible through the raw() method. Note that the response is subject to change across server versions and therefore should be properly checked before being used.
