Introducing native histogram support in Amazon Managed Service for Prometheus

If you run Kubernetes or microservices workloads on AWS, you probably track latency, request durations, and other value distributions with Prometheus histograms. To do that with classic histograms, you predefine a set of bucket boundaries, and Prometheus emits one time series per boundary plus a sum and a count. A single latency histogram with 20 buckets becomes 22 active time series.
