I'm trying to interface a large Scala + Akka + PlayMini application with an external REST API. The idea is to periodically poll (basically every 1 to 10 minutes) a root URL and then crawl through sub-level URLs to extract data which is then sent to a message queue.

I have come up with two ways to do this:

1st way

Create a hierarchy of actors to match the resource path structure of the API. In the Google Latitude case, that would mean, e.g.

In this case, each actor is responsible for polling its associated resource periodically, as well as creating / deleting child actors for next-level path resources (i.e. actor 'latitude/v1/location' creates actors 1, 2, 3, etc. for all locations it learns about through polling of https://www.googleapis.com/latitude/v1/location).

2nd way

Create a pool of identical polling actors which receive polling requests (containing the resource path) load-balanced by a router, poll the URL once, do some processing,
