type MergeChannelProcessor added in v0.8.4 

type MergeChannelProcessor struct {
	// contains filtered or unexported fields
}

This struct is responsible for merging responses from multiple response channels and controlling the concurrency of querying by giving away `concurrency' channels at any given time. This is used in the coordinator to merge the responses received from different shards, which could be remote or local.

func NewMergeChannelProcessor added in v0.8.4

Closes MergeChannelProcessor, this method has to make sure that all responses are received from the response channels. This is important since the protobuf client may block trying to insert a new response which will cause the entire node to stop receiving remote responses.

func (*MergeChannelProcessor) NextChannel added in v0.8.4 

func (p *MergeChannelProcessor) NextChannel(bs int) (chan<- *protocol.Response, error)

Returns a new channel with buffer size `bs'. This method will block until there are channels available to return. Remember MergeChannelProcessor controls the concurrency of the query by guaranteeing no more than `concurrency' channels are given away at any given time.

func (*MergeChannelProcessor) ProcessChannels added in v0.8.4 

func (p *MergeChannelProcessor) ProcessChannels()

Start processing the channels that are yielded by NextChannel() and yield the Series in the responses to the next Process.
