示例1: waitForFilteredReplication

func (wr *Wrangler) waitForFilteredReplication(sourcePositions map[*topo.ShardInfo]myproto.ReplicationPosition, destinationShards []*topo.ShardInfo) error {
	wg := sync.WaitGroup{}
	rec := concurrency.AllErrorRecorder{}
	for _, si := range destinationShards {
		wg.Add(1)
		go func(si *topo.ShardInfo) {
			for _, sourceShard := range si.SourceShards {
				// we're waiting on this guy
				blpPosition := blproto.BlpPosition{
					Uid: sourceShard.Uid,
				}

				// find the position it should be at
				for s, pos := range sourcePositions {
					if s.Keyspace() == sourceShard.Keyspace && s.ShardName() == sourceShard.Shard {
						blpPosition.Position = pos
					}
				}

				log.Infof("Waiting for %v to catch up", si.MasterAlias)
				if err := wr.ai.WaitBlpPosition(si.MasterAlias, blpPosition, wr.ActionTimeout()); err != nil {
					rec.RecordError(err)
