@hugoabonizio you don't have to support the current "implementation" of the response. If we decide to use RESP then we get rid of everything else. Don't worry about that.

@marceloboeira Alright, I'll replace the current protocol in this branch.

@hugoabonizio any updates on this one? I was thinking about using redis-benchmark¹ to figure it out how fast are we 😄.

Hi @marceloboeira!
I managed to run redis-cli connecting to BoJack and running the commands seamlessly, but I got stuck in testing. The test suite sometimes get stuck and I didn't find the reason yet.
I want to return to this issue soon, I'm not too far of making redis benchmark run (at least for GET/SET commands that are the same in both Redis and BoJack). 😃
