> once saw an app that did bidirectional RPC over message queues
Haha I've seen this anti-pattern too (although I think it's in the enterprise patterns book??). It would bring production to a grinding halt every night. Another engineer and I stayed up all night and replaced it with simple REST API.
I once saw a REST API built with bidirectional queues. There was a “REST” server that converted HTTP to some weird custom format and an “app” server with “business logic”, with tons of queues in between. It was massively over complicated and never made it to production. I won’t even describe what the database looked like.
