Redis-compatible Server
Rust, mio, RESP, AOF
2026 · Active
Rust Redis-style in-memory key-value server that speaks RESP2 and implements non-blocking TCP I/O, pipelining, binary-safe storage, TTL expiry, AOF persistence, memory accounting, and configurable eviction policies.
Supports PING, ECHO, SET, SET EX, GET, DEL, EXISTS, EXPIRE, TTL, and INFO over RESP-compatible TCP.
Separates protocol parsing, command dispatch, storage, persistence, and the mio event loop for testable internals.
Implements lazy and active expiry, AOF startup replay with fsync policy controls, and SIEVE-style second-chance eviction.
Comparable-command benchmark on Apple M4 averages about 243k req/s, roughly matching Redis under the same no-pipeline local test profile.
Test suite covers RESP parsing, commands, expiry, eviction, pipelining, memory accounting, and AOF replay.

Lorust
Rust, Tokio, RustPython, TOML
2024-2026 · Active
Rust HTTP load generator with direct CLI tests and TOML/JSON flow execution, rate or duration scheduling, thresholds, rich timing metrics, and RustPython-powered scripting between actions.
Supports request-count and duration modes, configurable rate, headers, body, method, timeout, redirect limits, and failed response body truncation.
Thresholds can fail the process on error rate, p95 or p99 latency, or minimum RPS while still writing raw metrics.
Flow files model virtual-user tasks with spawn-rate expressions, ordered HTTP steps, thresholds, variables, and scripting hooks.
Outputs a human summary and sorted per-request JSON metrics including DNS, connect, TLS, start-transfer, elapsed, and redirect timings.
