Workers Analytics Engine

Analytics Engine is a write-from-Workers time-series store you query with SQL over HTTP. Write a data point per event (with dimensions and metrics), then slice it however you like later. It’s cheap, it scales without thought, and it fills the “I want metrics about my thing without running a metrics stack” niche perfectly.

It works well for per-customer usage counters, feature adoption tracking, and internal dashboards. The SQL API plugs into almost anything, including Grafana.

You do need to understand the sampling before trusting the numbers. At high volumes, queries return estimates with a sample interval that you have to account for. That’s fine for trends and dashboards, but wrong for billing-grade counts. The fixed retention window and bring-your-own-dashboard approach keep it at a 7, albeit one I’m fond of.
