示例1: doVerb
import org.apache.cassandra.service.StorageProxy; //导入方法依赖的package包/类
public void doVerb(final MessageIn<CounterMutation> message, final int id)
{
final CounterMutation cm = message.payload;
logger.trace("Applying forwarded {}", cm);
String localDataCenter = DatabaseDescriptor.getEndpointSnitch().getDatacenter(FBUtilities.getBroadcastAddress());
// We should not wait for the result of the write in this thread,
// otherwise we could have a distributed deadlock between replicas
// running this VerbHandler (see #4578).
// Instead, we use a callback to send the response. Note that the callback
// will not be called if the request timeout, but this is ok
// because the coordinator of the counter mutation will timeout on
// it's own in that case.
StorageProxy.applyCounterMutationOnLeader(cm, localDataCenter, new Runnable()
{
public void run()
{
MessagingService.instance().sendReply(WriteResponse.createMessage(), id, message.from);
}
});
}
