A zero-contention, thread-safe metrics aggregator for high-performance Python applications.
Project description
Pylight Metrics
Zero-Contention, High-Performance Observability for Python.
pylight-metrics is a thread-safe metrics aggregator designed for high-throughput applications. It uses Thread Local Storage (TLS) to buffer metrics, ensuring your application's critical path remains lock-free.
Features
- 🚀 Zero-Contention: Writes to thread-local buffers; global locks are only acquired during infrequent merges.
- 📊 Rich Statistics: Calculates P50, P90, P99, Standard Deviation, and Counts.
- 📈 Exporters: Supports JSON, Prometheus, and CSV (Excel) formats.
- 🔌 Drop-in Ready: Use decorators like
@fast_timerand@count_calls.
