🛠️ FEATURED SYSTEMS ENGINE & CLI · valkey-probe
High-performance Valkey & Redis Cluster Hash-Slot Topology Validator & Diagnostic CLI. Built with zero external dependencies in Python 3.10+.
# ⚡ Install and validate cluster slot integrity & skew in sub-milliseconds
pip install git+https://github.com/RajGahoi/valkey-probe.git
valkey-probe inspect /path/to/nodes.conf- Exact CRC16 Polynomial (0x1021): Byte-exact XMODEM hash slot computation with
{hash_tag}extraction rules. - 16,384 Slot Integrity Guard: Detects unassigned slot holes, overlapping collisions, dead masters, and orphan replicas.
- CI/CD & Monitoring Surface: Outputs interactive ANSI terminal cards, structured JSON for deployment gates, and native Prometheus text exposition metrics.
🚀 Optimizing Async Event Loops: How I Dropped Server Shutdown Latency from 200ms to <1ms in Uvicorn
An in-depth case study breaking down how replacing periodicasyncio.sleeppolling with a wakeableasyncio.Eventsynchronization primitive in Kludex/uvicorn#3238 reduced idle stop latency by >200x (from ~200ms to 0.42ms). Includes Mermaid sequence diagrams, kernel timer analysis, and benchmark distributions.
Production-grade driver internals, cluster topology diagnostics, and UI architecture contributed to valkey-io/valkey-admin.
