Bifrost

Bifrost is a Redis-like in-memory database server implemented in Rust. It uses the RESP (Redis Serialization Protocol) for client-server communication and supports basic Redis commands.

Features

• In-memory key-value storage
• RESP (Redis Serialization Protocol) support
• Concurrent connections using async I/O
• Thread-safe storage using parking_lot::RwLock

Building

To build the project, you'll need Rust and Cargo installed. Then run:

cargo build --release

Running

To start the Bifrost server:

cargo run --release

By default, the server listens on 127.0.0.1:6379.

Testing

Run the test suite with:

cargo test

Supported Commands

Bifrost currently supports the following Redis commands:

• PING - Test connection
• ECHO <message> - Echo back a message
• GET <key> - Get the value of a key
• SET <key> <value> - Set the value of a key
• DEL <key> - Delete a key
• EXISTS <key> - Check if a key exists
• INCR <key> - Increment the integer value of a key
• DECR <key> - Decrement the integer value of a key

Connecting

You can connect to Bifrost using any Redis client. For example, using redis-cli:

redis-cli -p 6379

Example commands:

127.0.0.1:6379> PING
PONG
127.0.0.1:6379> SET mykey "Hello"
OK
127.0.0.1:6379> GET mykey
"Hello"
