Go Redis Server

A weekend project implementing a partial, in-memory RESP2-compliant Redis server in Go. Implementation tested against the official go-redis client.

Build and Execute

# Run without building
go run main.go 
# Run Test
go test -v 
# Build Docker Container
docker build -t go-redis-server:latest . 
# Run the container 
docker run -d -p 6379:6379 --name go-redis-server \ 
  -e REDIS_PASSWORD=your_redis_password \
  -e REDIS_PORT=6379 \
  go-redis-server

Resources & Libraries Used

• Redis serialization protocol specification
• List of Redis Commands
• Offical Redis Go Client
• Test Containers

Implemented Protocol Commands

• AUTH - AUTH command on the client
• GET - Get value of a key
• SET - Set a value of a key
• DEL - Delete a key
• EXISTS - Check if key exists
• EXPIRE - Sets a keys expiration
• TTL - Get time to live of key
• RENAME - Rename a keys value
• APPEND - Append value to a key
• INCR - Increment value of key
• DECR - Decrement value of key
• PING - PONG!
• INFO - Debug info about the server.

Caveats

1. Theres no enforcement on integer overflows.
2. No timeouts, very little validation of input. Theoretically commands can hang forever.
3. There are several sub-operations on the commands that still need implementing.
