Cap'n Proto 0.6 released – 2.5 years of improvements
This might be a contrarian view, maybe I'm misunderstanding it. To me, much of message passing is not performance critical, so it would be well served by JSON/YAML/XML for easy implementation/testing/debugging. If one needs performance, he can just send bytes over, which can be (de)serialised in a (couple) dozen SLOC. Sure, when you're talking about very complex structures, RPC, dynamic schemas etc., then you might opt for something like this, but let's be honest - that's quite a minority of current users, isn't it?<p>I never minded these frameworks, but then I wanted to write a few parsers for some file formats and they used Thrift/Flatbuffers to encode a few ints, which seemed like a major overkill. There was no RPC, no packet loss, no nothing.
