I'm a little sad that I got laid off from a previous job for a variety of reasons, but one big one was that there were discussions of letting me open source some very big changes I had made to the Kafka Streams library.

I rewrote a lot of stuff while keeping the API mostly compatible, focusing on emphasizing non-blocking IO with backpressure semantics available if necessary. It was really cool and enabled a lot of interesting stuff involving the state store and mixing+matching blocking and non-blocking IO in a way that was still relatively performant. I think it was really neat and it's one of the projects I am most proud of because I was able to squeeze out performance in a lot of places that were non-obvious.

I was pushing to allow us to release it to Github and/or make a PR to the upstream Kafka Streams project, but sadly they did layoffs before that was completed and afterwards there was really no "champion" to do that, so it's stuck in proprietary land.

I might still do it from scratch and FOSS it, it's been long enough to where I think I wouldn't get in trouble if I rewrote it and released it (there weren't any patents or anything attached to it), and there are a few things I'd like to change anyway (like getting rid of the dependency of Vert.x). Maybe if I ever get a week off I'll do that.

I miss working at a place which allowed this.

Some employers get tangled up in just the legal review process.

Once I asked permission to submit a patch to a project and it had quite an interesting email trail. It came down to a single question: if the patch was written during hours billed to a customer for the purpose of fixing a bug in a deliverable product, and the library being patched had to be recompiled and delivered with the source code, and the contract states that all work and intellectual property associated to the product would be transferred to the customer, do we have authority to release the patch in the public domain?

Legal didn’t want to answer it.

I think that's a generally good approach and a fantastic example of framing things professionally but also doesn't fix the core of the problem, which I see problematic if leadership of an engineering-focused company doesn't understand immediately.

Luck with your employer also plays a big part in how you approach this too.

“Sure, let me run this through the compliancy team. Just to make sure there’s no intellectual property infringement. Which repository and issue, exactly?”
