# redis-server

Redis is an in-memory key-value NoSQL database.

This is a coding challenge from https://codingchallenges.fyi/challenges/challenge-redis/.  

It aims to build a lite version of Redis with all the functionality of the first version of Redis.

The server was built using Python (but prefer C, Rust or Golang for performance) and test-driven development approach.

Run server : `python redis_server.py`  

### 1 - protocol  

- RESP is the protocol used to communicate with a Redis server

- Clients send commands to a Redis Server as a RESP Array of Bulk Strings

- Server replies with one of the RESP type

- Need to implement a functionality to serialize and deserialize messages

### 2 - server  

- Create a server that listens on port `6379`

- Sockets, Threads, Concurrency

- Use redis-cli to communicate with redis server

### 3 - commands

- PING

- ECHO

- SET (with expiration options)

- GET

- EXISTS

- DEL

- INCR

- DECR

- LPUSH

- RPUSH

- SAVE

### 4 - performance check

- You can use redis-benchmark to check concurrency and performance

- The redis-benchmark utility simulates running commands done by N clients while at the same time sending M total queries.

### Tips

I use https://try.redis.io/ to compare my lite version with Redis
