Building My Own Redis

What will I be building currently?

• Binding to a TCP port and listening for connections
• Responding to basic commands like PING and ECHO
• Parsing the Redis Protocol (RESP) from client requests
• Handling multiple clients concurrently
• Implementing the SET and GET commands to store and retrieve data.

Note: This is a challenge from codecrafters.io

Things to be done

• Allow handling concurrent clients
• Implement a codec for framing
• Implement the data flow:
  read bytes -> parse frames -> map to commands -> run command -> response frames -> write bytes
• Implement ECHO and PING commands
• Implement SET and GET commands
• Implement Expiry
• Add structured error handling
• Add extensive unit tests
