Hi all

I did a little talk on Celery vs. Crossbar at PyConZA 2016.

Hi Adam,

Hi all

I did a little talk on Celery vs. Crossbar at PyConZA 2016.

Nice, nice! Thanks for sharing (just watched and retweeted). Ah, and cool T-shirt;)

For me your talk is especially interesting (obviously, I know Crossbar.io), because you lose sight when being deeply involved with something, and hence the "power user view" is invaluable. Like both the good parts and the bad parts - yeah, absolutely.

I totally agree with the Crossbar.io bad parts .. docs still lacking, clustering overdue. We're working on both!

Rgd. clustering, I'd like to stress that scaling app components is there already - what is missing is scaling the router itself. Given the feature set of Crossbar.io, this is non-trivial.

Let me also promote this (if you haven't stepped over):

The "max concurrency" and "call queueing" is a very powerful feature - and often required in real-world scaling-out app components (at least in our own use of this approach in customer projects).

Thanks for the awesome project Tavendo, keep up the good work :slight_smile:

Thanks for the nice words=) Certainly encouraging, and yeah, we'll continue work - we've just started!

Cheers,
/Tobias

Thanks for the retweet, glad you enjoyed the talk.

I was stressing over it a lot because I only got it done and ready to go a week before the conference. Despite vowing to have it done a month before, work intervened and I lost some time :frowning:

I did try to cover some basic aspects of component scaling in my talk but ended up glossing over some details I could have mentioned. For example, the call queueing and max concurrency follow on naturally from the shared registrations but I ended up not covering those details because I wanted to give a slightly wider picture of Crossbar and WAMP. I imagine that while many people have heard of Celery, those familiar with Crossbar and WAMP are much fewer.

Thanks for the YT link, I saw it a few months back and it’s part of the reason why I decided to do a talk on Crossbar. I was very excited when I discovered Crossbar because finding a good WS solution for Python has been tricky and discovering it does more than the basic WS was wonderful.
