ZooKeeperBroker

public ZooKeeperBroker(AbstractGraphDatabase graphDb,
                       Map<String,String> config,
                       ResponseReceiver receiver)

Method Detail

logStatus

public void logStatus(StringLogger msgLog)

Specified by:

logStatus in interface Broker

Overrides:

logStatus in class AbstractBroker

getClusterStoreId

public StoreId getClusterStoreId(boolean firstTime)

Description copied from interface: Broker

Asks the cluster for and returns the storeId currently shared by the cluster members or a new one if none is there.

Specified by:

getClusterStoreId in interface Broker

Overrides:

getClusterStoreId in class AbstractBroker

Parameters:

firstTime - False if it should timeout after a session interval passes - expected to be true in the same scenarios where Broker.bootstrap() is called instead of Broker.getMasterReally(boolean)

Returns:

The storeId existing in the cluster or a new one if none is found
