Redis FAQ or: what you learn when idling in #redis

First: this here is the unofficial FAQ, only containing things that come up by users in the IRC channel #redis on Freenode. There's also a more official FAQ. This document is also available on my site.

X is weird in my instance. Can you help?

Maybe. To better help please give the following info:

Output of redis-cli INFO

RESP3 specification

Versions history:

1.0, 2 May 2018, Initial draft to get community feedbacks.

Background

The Redis protocol has served us well in the past years, showing that, if carefully designed, a simple human readable protocol is not the bottleneck in the client server communication, and that the simplicity of the design is a major advantage in creating a healthy client libraries ecosystem.

Yet the Redis experience has shown that after about six years from its introduction (when it replaced the initial Redis protocol), the current RESP protocol could be improved, especially in order to make client implementations simpler and to support new features.
