	longPollTimeout time.Duration,
	clients common.ClientCache,
	lb LoadBalancer,
) Client

NewClient creates a new history service TChannel client

type LoadBalancer added in v0.7.0

type LoadBalancer interface {
	// PickWritePartition returns the task list partition for adding
	// an activity or decision task. The input is the name of the
	// original task list (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(
		domainID string,
		taskList shared.TaskList,
		taskListType int,
		forwardedFrom string,
	) string

	// PickReadPartition returns the task list partition to send a poller to.
	// Input is name of the original task list as specified by caller. When
	// forwardedFrom is non-empty, no load balancing should be done.
	PickReadPartition(
		domainID string,
		taskList shared.TaskList,
		taskListType int,
		forwardedFrom string,
	) string
}
