Types

type Client

type Client interface {
	// Close closes table client
	Close(ctx context.Context) error

	// Do provide the best effort for execute operation
	// Do implements internal busy loop until one of the following conditions is met:
	// - deadline was canceled or deadlined
	// - retry operation returned nil as error
	// Warning: if deadline without deadline or cancellation func Retry will be worked infinite
	Do(ctx context.Context, op Operation, opts ...Option) (err error)
}
