type BatchConfig struct {
	// BufferSize defines a size of the buffering queue.
	BufferSize int
	// MaxBatchSize defines maximum size of a batch.
	MaxBatchSize int
	// MaxBatchWait indicates the maximum interval between two batches.
	MaxBatchWait time.Duration

	// ThrottleEnable defines whether throttling will be applied to the batching process.
	ThrottleEnable bool
	// ThrottleQPS defines the allowed rate of batches per second sent to the delegate backend.
	ThrottleQPS float32
	// ThrottleBurst defines the maximum number of requests sent to the delegate backend at the same moment in case
	// the capacity defined by ThrottleQPS was not utilized.
	ThrottleBurst int

	// Whether the delegate backend should be called asynchronously.
	AsyncDelegate bool
