The Redis ChallengeEarly Access
In this challenge, you’ll build an application that can speak the Redis protocol, and is capable of serving basic commands like PING, ECHO, SET and GET. Along the way, you’ll learn about TCP servers, event loops and more.
This challenge has 7 stages.
Bind to a port
In this stage, you’ll start a TCP server on port 6379, which is the default port that Redis uses.
Respond to multiple PINGs
In this stage, you’ll respond to multiple PING commands sent by the same client.
Handle concurrent clients
In this stage, you’ll add support for multiple concurrent clients to your Redis server. To achieve this you’ll use an Event Loop, like the official Redis implementation does.
In this stage, you’ll add support for setting a key with an expiry. The expiry is provided using the “PX” argument to the SET command.
