Beats Valkey on GET and SET benchmarks while guaranteeing memory safety with Rust.

Strengths
  • Passes Valkey's official test suite, ensuring genuine protocol compatibility beyond mocks.
  • Outperforms Valkey 9.1.0 on PING, GET, and SET in single-node benchmarks.
  • Uses rustls for TLS, eliminating C-based cryptography vulnerabilities in transport layer.
Weaknesses
  • Single-node only; lacks clustering support in Dragonfly or Redis Enterprise.
  • Performance drops below Valkey on XADD, FCALL, limiting stream and scripting use.
