Native histograms store distributions in a single time series with automatic resolution adjustment, enabling more accurate percentile calculations for latency and duration metrics without manual bucket boundaries. This reduces active series count significantly compared to classic histograms.

The service supports incremental adoption alongside classic histograms and charges only for populated buckets, optimizing cost efficiency. This capability is available in all regions offering Amazon Managed Service for Prometheus, enhancing observability for DevOps and site reliability engineers.
