ResourceMirror

trait ResourceMirror[IO[_], T] extends ReconcileSource[IO, T]

ResourceMirror provides:

  • A snapshot of the current state of a set of resources
  • A stream tracking the ID of changed resources. Subscribers to this stream MUST NOT backpressure, as that could cause the watcher (and other observers) to fall behind. In practice, this is typically consumed by Dispatcher, which doesn't backpressure.
