func Poll ¶

func Poll(
	ctx context.Context,
	logger logging.Log,
	name string,
	interval, stagger time.Duration,
	fn func(context.Context) (bool, error),
)

Poll runs fn on a fixed interval until ctx is cancelled. When fn reports it did work, Poll runs it again immediately, so a backlog drains at full speed. An error is logged and the loop continues.

stagger delays the first run, so loops sharing an interval de-synchronize. name identifies the loop in its log lines and on its spans.

Give it the boot context: a request context dies at the server's own timeout.
