Method Detail

getIdentityKey

static String getIdentityKey(Identity id)

Returns a identity key for the given id.

getNodeKey

static String getNodeKey(long nodeId,
                         Identity id)

Returns a node key for the given nodeId and id.

getPartialNodeKey

static String getPartialNodeKey(long nodeId)

Returns a node key for the given nodeId; used for iterating through a node for all identities assigned to it.

getStatusKey

static String getStatusKey(Identity id,
                           long nodeId,
                           String serviceName)

Returns a status key for the given id, nodeId, and serviceName. The status mappings are held per identity per node.

getPartialStatusKey

static String getPartialStatusKey(Identity id,
                                  long nodeId)

Returns a status key for the given id and nodeId. Used for finding all status entries for an identity on a particular node.

getPartialStatusKey

static String getPartialStatusKey(Identity id)

Returns a status key for a given id. Used for finding all status entries for an identity (on all nodes).
