BetterKV

BetterKV is a Redis-compatible in-memory key-value store written in Rust and built for low latency, high throughput, and predictable performance.

Current status: open beta.

• Redis protocol compatible for a growing command surface
• Multi-threaded server architecture built on Tokio
• Sharded in-memory engine optimized for concurrent access
• Persistence, Pub/Sub, transactions, scripting, and more are in active development across the workspace
• Authentication and ACL support are still beta and are not recommended for production use yet

Connect with redis-cli:

redis-cli -h 127.0.0.1 -p 6379 ping
# PONG

Run the interactive CLI:

cargo run -p betterkv-cli -- --host 127.0.0.1 --port 6379

Run the benchmark tool:

cargo run -p betterkv-benchmark -- -h 127.0.0.1 -p 6379 -c 100 -n 100000 -P 16
