public boolean startInner()
                   throws Exception

Specified by:

startInner in class AbstractVeniceService

true if the service is completely started, false if it is still starting asynchronously (in this case, it is the implementer's responsibility to set AbstractVeniceService.serviceState to AbstractVeniceService.ServiceState.STARTED upon completion of the async work).

Throws:

Exception

stopInner

public void stopInner()
               throws Exception

Specified by:

stopInner in class AbstractVeniceService

Throws:

Exception

 long offset,
 boolean skipDIV)

Skip admin message with specified offset for the given cluster.
