Unfiltered at Meetup?

[chris_lewis]

I wanted to ask on the list, assuming Nathan is at liberty to divulge, to what extent Meetup is using Unfiltered. It's public that Unfiltered powers the streaming api, but Nathan's tweet yesterday caught my attention. From the link, it seems that Unfiltered is also serving, or at least playing some role in serving, the primary front-facing app.

So... I'm interested :-). Nathan are you able to elaborate at all on the what's and how's of that tweet?

I'm pretty sure it's the side bar with the stream of RSVPs. Chrome's web inspector is telling me there's websocket to the streaming API.

ws://stream.meetup.com/2/rsvps

Pretty cool stuff.

Nice catch! I didn't notice that. I'd be interested to hear some metrics after a few days, but so far seems to be a testament to Unfiltered+netty as a solid platform for async http.

I can't promise metrics yet, but we will get a post up about the front end of http://www.meetup.com/tour/ on the engineering blog soon.

There's the websocket interface that you've found, but if you look at the same page in firefox or anything other than Chrome or Safari you'll see it's doing long-polling instead. We have one post on websockets [1] and one before that on the original http chunked stream [2].

I haven't written about how the long polling backend works yet; I did present it to ny-scala last month. It seemed like people weren't that into it because I used too many synchronized blocks and not enough actors (just kidding... Dag) so I'm actually going to have a go at doing it with fancier concurrency structures, and seeing if it I can break that.

I was more comfortable avoiding the possible overhead or bugs of any concurrency library for the initial version, but it's true that the complexity of doing it by hand sucks. We can't really build much more on top of it before I can't read my own code. So, more to come on that front I hope.

Very cool. I was curious about long-polling chunked streams; bummer I missed that talk!
