Very nice. Helped me understanding Storm better. To bad that the demo was in Java made everything more compicated. Its kind of obvious that the Strom was written in Clojure. The Java Api seams to be a rather thin layer ontop of the clojure version. I cant imagen that you would have the same serialization problems in clojure, Nathan would of have fixed this. It will probebly be fixed in the java layer soon enought.

Edit: "I cant imagen that you would have the same serialization problems in clojure, Nathan would of have fixed this." seams like the wrong formulation. I didn't want to criticize. I guessed that the problem was in the Java API witch probebly has less testing then the clojure version but it seams to be a design decision.

I definitely get the sense that Java is a first-class citizen in the Storm world, even though it's written in Clojure. There's also the fact that I know next to nothing about Clojure (although I love Scheme, so maybe this'd be a good time to pick it up), but I definitely wouldn't mind doing a video on Storm's multilang support for other languages that I do understand (like Python or Ruby).

As for the serialization problems, that's mostly just a lack of documentation :( There was no problem with it once I learned how to register a serializer with Storm.

I based my argument on the observation that there were alot of hash maps and that alot of things weren't typed. Two things that are very clojury.

Edit: I don't read alot of java code but I guess that Hash maps aren't that common in most java programmes.

The serialization system needs more documentation, which I'll work on tonight. There are good reasons for every decision that was made with serialization. The feedback from this screencast was invaluable.

Are you saying that one would have the same "problem" in Clojure or is it just in the Java API?

There's no actual problem. It just needs to be documented and explained. I'm travelling today, so I can't write the doc till later.

Been wanting to checkout Storm since the announcement - looking forward to watching the rest of this...

Is there an example of a storm cluster in Clojure somewhere? I could only find examples for Java, Python and Ruby on github.

I'm going to try to get an example + docs out in the next few weeks.

Excellent, thanks!

I found this gist from Nathan helpful: https://gist.github.com/1228302

You'll need the RandomSentenceSpout from https://github.com/nathanmarz/storm-starter

Would love to see a Clojure version of this

The best part is at the end when he plays back all 200K Emmy tweet in 6 minutes and says "I feel like I'm narrating a horse race"! Hilarity ensued.

I love how the action unfolds at the end, each show competing for most buzz across Twitter while the tweets are streaming by! Nice work on lining up the commentary with events from the Emmys!
