PromQL Meets Pinot: Building PromQL Natively in StarTree Cloud | RTA Summit 2025

While Prometheus has become the de-facto standard for metrics storage and querying, many organizations struggle with its scalability limitations. Explore how we built a native PromQL query engine directly into Apache Pinot, eliminating the need for intermediate translation layers. We'll dive deep into how we implemented PromQL's time-series semantics, functions, and operators natively in Pinot while maintaining its performance characteristics. This native integration, along with our custom Grafana plugin, allows users to leverage Pinot's scalability and performance while seamlessly building Grafana dashboards using their existing PromQL workflows.

StarTree turns raw data streams—like clickstreams, logs, vector embeddings, and sensor data—into real-time analytics. It powers customer-facing data products, agent-facing data products, and operational intelligence. Apache Pinot™ delivers real-time analytics by design, rather than extension—built from the ground up to ingest massive data streams with millisecond freshness, execute sub-second aggregations, and support tens of thousands of queries per second. Pinot achieves this while radically reducing infrastructure costs by scanning less data and extreme compression. StarTree was founded by the core software engineering team and inventors of Apache Pinot™, which currently powers hundreds of user-facing applications at companies across industries, including Uber, LinkedIn, Stripe, Target, 7Eleven, NuBank, Etsy, Walmart, Together AI, and more. #apachepinot #realtimeanalytics #startree
