示例1: Query

func (self *ShardData) Query(querySpec *parser.QuerySpec, response chan<- *p.Response) {
	log.Debug("QUERY: shard %d, query '%s'", self.Id(), querySpec.GetQueryStringWithTimeCondition())
	defer common.RecoverFunc(querySpec.Database(), querySpec.GetQueryStringWithTimeCondition(), func(err interface{}) {
		response <- &p.Response{
			Type:         p.Response_ERROR.Enum(),
			ErrorMessage: p.String(fmt.Sprintf("%s", err)),
		}
	})

	// This is only for queries that are deletes or drops. They need to be sent everywhere as opposed to just the local or one of the remote shards.
	// But this boolean should only be set to true on the server that receives the initial query.
	if querySpec.RunAgainstAllServersInShard {
		if querySpec.IsDeleteFromSeriesQuery() {
			self.logAndHandleDeleteQuery(querySpec, response)
		} else if querySpec.IsDropSeriesQuery() {
			self.logAndHandleDropSeriesQuery(querySpec, response)
		}
	}

	if self.IsLocal {
		var processor engine.Processor = NewResponseChannelProcessor(NewResponseChannelWrapper(response))
		var err error

		processor = NewShardIdInserterProcessor(self.Id(), processor)

		processor, err = self.getProcessor(querySpec, processor)
		if err != nil {
			response <- &p.Response{
				Type:         p.Response_ERROR.Enum(),

		defer self.store.ReturnShard(self.id)

		log.Debug("Processor chain:  %s\n", engine.ProcessorChain(processor))

		err = shard.Query(querySpec, processor)
		// if we call Close() in case of an error it will mask the error
