Based on excellent write-up from https://www.elttam.com.au/blog/ruby-deserialization/

Doesn't work to use YAML.dump(payload) in the above script. This only produces the following YAML, which is worthless:

--- !ruby/object:Gem::Requirement
requirements:
- - ">="
  - !ruby/object:Gem::Version
 version: '0'

Creating a redis Module in 15 lines of code!

A quick guide to write a very very simple "ECHO" style module to redis and load it. It's not really useful of course, but the idea is to illustrate how little boilerplate it takes.

Step 1: open your favorite editor and write/paste the following code in a file called module.c

#include "redismodule.h"
/* ECHO <string> - Echo back a string sent from the client */
int EchoCommand(RedisModuleCtx *ctx, RedisModuleString **argv, int argc) {

HTTP Streaming (or Chunked vs Store & Forward)

HTTP Streaming (or Chunked vs Store & Forward)

The standard way of understanding the HTTP protocol is via the request reply pattern. Each HTTP transaction consists of a finitely bounded HTTP request and a finitely bounded HTTP response.

However it's also possible for both parts of an HTTP 1.1 transaction to stream their possibly infinitely bounded data. The advantages is that the sender can send data that is beyond the sender's memory limit, and the receiver can act on
