Proposal: rSocket support

[kamilgregorczyk]

It would be great if micronaut could support rSocket with rSocket-rpc lib, it seems to have better adoption than gRpc as it's fully reactive and much more performant as it does not use HTTP

Hi folks, Is there any news on this topic? What we are waiting for?

[graemerocher]

Just a matter of priorities, contributions welcome though!

much more performant

this is not (and never was) accurate - e.g. performance (throughput) of spring-rsocket(cbor) over TCP is substantially worse than grpc-java for streaming interactions, and +- the same for request-response. rsocket/rsocket-rpc-java is abandoned project - I am not sure its generated code even compiles.

Additionally rsocket/rsocket-java - which is the basis for rsocket/rsocket-rpc-rxjava - is vulnerable to several
trivial denial-of-service attacks (memory overflow, file descriptors exhaustion) 1, 2, 3, 4 - so such servers are unsafe with
3rd party clients. They were reported to Springframework team who are main advocates & seems were maintaining rsocket/rsocket-java after big US companies lost interest - only 1 vuln was being worked on (though no release was made for 5 months now), other vulnerabilities are ignored.
