RSocket Support

[emax19]

The RSocket technology has burst into the IT market. It's a very promising technology already used by many big products. So, it will be very helpful to start to support that, please take a look.

Thanks for making this issue! If anyone else is interested, feel free to give 👍 to the post above. FWIW, this is the first time I'm hearing about RSocket and it seems interesting, though I doubt it has very wide adoption yet.

At some future point, we might add support for RSocket in the k6 core, but for the foreseeable future, an xk6 extension would probably be a better fit. There seems to be at least one Go library for it (https://github.com/rsocket/rsocket-go), so here are some links with details about xk6:

• https://github.com/k6io/xk6
• https://k6.io/blog/extending-k6-with-xk6

The only caution here is that k6 doesn't yet have native event loops in every VU, and I imagine RSocket support would be a bit more synchronous because of it. Follow #882 for updates on the topic.

As there are currently no plans for RSocket to become part of the k6 core and it doesn't seem like it might in the future I am closing this issue.

As mentioned in the previous comment this likely should be an extension. I did try to find if someone has made one, but unsuccesfully :(.
