Proximo

Proximo is a proxy for multiple different publish-subscribe queuing systems.

It is based on a GRPC interface definition, making it easy to create new client libraries. It already supports a number of popular queueing systems, and adding new ones is intended to be simple.

Goals

Expose multiple consumer (fan out) semantics where needed Minimise overhead over direct use of a given queuing system Allow configuration of the underlying queue system via runtime configuration of Proximo Allow replacement of a queueing system with no change to the Proximo client applications Enabling easy creation of client libraries for new languages (anything that has GRPC support)

Non goals

Exposing specific details of the underlying queue system via the client API
