Types

type Client

type Client interface {
	matchingservice.MatchingServiceClient
}

Client is the interface exposed by matching service client

func NewClient

func NewClient(
	timeout time.Duration,
	longPollTimeout time.Duration,
	clients common.ClientCache,
	lb LoadBalancer,
) Client

NewClient creates a new history service TChannel client

func NewMetricClient

func NewMetricClient(client Client, metricsClient metrics.Client) Client

NewMetricClient creates a new instance of Client that emits metrics

func NewRetryableClient

func NewRetryableClient(client Client, policy backoff.RetryPolicy, isRetryable backoff.IsRetryable) Client

NewRetryableClient creates a new instance of Client with retry policy

type LoadBalancer

type LoadBalancer interface {
	// PickWritePartition returns the task queue partition for adding
	// an activity or workflow task. The input is the name of the
	// original task queue (with no partition info). When forwardedFrom
	// is non-empty, this call is forwardedFrom from a child partition
	// to a parent partition in which case, no load balancing should be
	// performed
	PickWritePartition(
		namespaceID string,
		taskQueue taskqueuepb.TaskQueue,
		taskQueueType enumspb.TaskQueueType,
		forwardedFrom string,
	) string

	// PickReadPartition returns the task queue partition to send a poller to.
	// Input is name of the original task queue as specified by caller. When
	// forwardedFrom is non-empty, no load balancing should be done.
	PickReadPartition(
		namespaceID string,
		taskQueue taskqueuepb.TaskQueue,
		taskQueueType enumspb.TaskQueueType,
		forwardedFrom string,
	) string
}

LoadBalancer is the interface for implementers of component that distributes add/poll api calls across available task queue partitions when possible

func NewLoadBalancer

func NewLoadBalancer(
	namespaceIDToName func(string) (string, error),
	dc *dynamicconfig.Collection,
) LoadBalancer

NewLoadBalancer returns an instance of matching load balancer that can help distribute api calls across task queue partitions
