	// ExecutionAPICountLimitOverride determines how many tokens each of these API calls consumes from their

	// the value is not set, then the method is not considered a long-running request and the number of concurrent
	// requests will not be throttled. The Poll* methods here are long-running because they block until there is a task
	// available. The GetWorkflowExecutionHistory method is blocking only if WaitNewEvent is true, otherwise it is not
	// long-running. The QueryWorkflow and UpdateWorkflowExecution methods are long-running because they both block
