simple-key-value-store

Task

The task is to build a TCP server that acts as a simple key-value store. The server should handle multiple client connections concurrently using asyncio.

Supported commands

GET <key>: Retrieves the value associated with a given key.

SET <key> <value>: Sets the value for a given key.

DELETE <key>: Deletes the key-value pair associated with a given key.

Requirements:

1. Server should handle multiple connections
2. Clients should be able to get the value of a key, set the value of a key, and delete a key-value pair.
3. Server should send appropriate error messages to the client if there is any issue
4. The server should persist the key-value stored in memory (e.g., using a dictionary).

Usage

Following would start a server in background.

$ python server.py &

Once server is started run single client or multiple clients as follows:

$ python client.py

$ python clients.py
