Show HN: Lightbus – Python/Redis Message Bus for Eventing and RPCs

Hi Hacker News. I started developing this over two years ago when I become dissatisfied with what I felt was a lack of good options for an easy-to-use Python messaging system. I didn’t think it would take this long (of course!), but I’ve certainly learnt a lot about messaging and distributed systems. I tracked my progress in issue number 1 on GitHub, and I feel pretty happy that I now have 98 of 98 tasks complete! [1]

I’ve been using this in production now for about a year and it has faired very well. I found a few weird bugs along the way, but it has felt stable for quite a while now. I’m therefore finally making an official release. I wanted to call this version 1.0, but I’m going to play it safe and call it 0.9 for a few months and see if anything crops up in other peoples’ environments.

Before embarking on this I spent a long time talking to other developers to see if anything similar existed. The most similar I could see was Nameko, but I didn’t feel like that ticked my boxes. Lahja is another one which I saw pop up more recently. I’ve also written a short comparison with Celery, as it something I’m often asked about [2].

I’ve also spent a lot of time writing up the docs. A crude word count indicates I’ve written 23,400 words of narrative documentation :o

I was also keen to not strictly limit this too Python. I’ve therefore documented the Redis interactions required for other languages to interface with Lightbus[3], albeit without the various niceties that Lightbus provides).

Constructive feedback is very welcome!
