About:
hdrhistogram_c is a high-performance C library for recording and analyzing latency and performance data with high dynamic range and low overhead. It provides compact, lossless histograms that can capture measurements across many orders of magnitude, from nanoseconds to days. This makes it ideal for performance-sensitive applications requiring precise latency tracking and statistical analysis.

Key Features:

High dynamic range recording from nanoseconds to days
Low memory footprint and overhead
Lossless compression of recorded data
Support for log-linear and linear value scaling
Thread-safe implementations and serialization utilities

Use Cases:

Performance monitoring and latency analysis in distributed systems
Benchmarking and profiling C/C++ applications
Real-time telemetry and metrics collection in embedded systems

Alternatives:

prometheus-histogram – Prometheus client libraries offer histograms but with fixed buckets and less dynamic range, suited for metrics aggregation rather than precise latency analysis.
tdigest – Provides approximate quantiles with high accuracy but focuses on streaming data analysis rather than high-resolution, lossless histograms.
