We're on a mission to build the best observability platform in the world for engineers to understand and scale their systems, applications, and teams. We operate at high scale—trillions of data points per day—providing always-on alerting, metrics visualization, logs, and application tracing for tens of thousands of companies. Our engineering culture values pragmatism, honesty, and simplicity to solve hard problems the right way. The Metrics Query team owns and operates the “read” side of Datadog's metrics platform. Our systems provide the APIs and interfaces for querying time series data. These systems parse, plan, execute, and cache trillions of queries per day. Our challenge is to efficiently and pragmatically scale these systems while continuing to add new capabilities that delight our customers.
