Rust benchmark demo

This repo contains a bunch of several implementation on the same logic:

• Implements a HTTP endpoint waiting for a JSON looking like {"id": 1, "data": "foo"} as a POST body
• Hash the .data field of the body using the Black2B hash function
• Retrieve a client from postgres using the .id as the key
• Build a JSON message with the client.name in the name field and the hash in the hash field
• Send this message on RabbitMQ
• Return this message in the HTTP response

Why?

For fun of course! Initially, the rust implementation was built for a presentation by @fistons but then he wanted to compare rust performance against other languages

Fnu! I want to add my favorite langage!

Easy! Create a subdirectory in this repo, with your code and a Dockerfile and add it to the docker-compose. Here are the infos and credentials for the others services:

• RabbitMQ:
  • host: rabbitmq
  • username: guest
  • password: guest
• Postgreql:
  • host: postgres
  • username: rust
  • password: rust

Then, just add your service in the docker-compose.yml file, binding a specific port to the host and let's roll!

What about the database model?

The database migration and filling is taking care of in the docker compose.

Here is the CREATE TABLE:

CREATE TABLE clients (
  id serial primary key,
  name varchar(100) not null unique
);

Please note that there is only one client loaded by the migration:

id	name
1	Uber Client

How to publish on rabbitmq?

• Exchange name: toRustDemo
• Routing key: rust

Have fun!

Implementations notes

• The reactive java implementation uses old fashion blocking jdbc because the postgres r2dbc driver is slow as hell
