brq 0.2.2

brq

This project is inspired by arq. Not intentionally dividing the community, I desperately needed a redis queue based on redis stream for work reasons and just decided to open source it.

You should also consider arq as more of a library: https://github.com/samuelcolvin/arq/issues/437
