Engineering Metrics Datastore

Overview of the engineering metrics datastore used by the Developer Experience section, covering CI execution, test execution, code coverage, performance tests, issues, and merge requests data

Instance

The Developer Experience section uses a ClickHouse instance for storing and querying large-scale engineering metrics data. ClickHouse is a column-oriented database optimized for analytical workloads, making it well-suited for the data it holds: CI execution, test execution, code coverage, performance tests, issues, and merge requests.

For technical documentation on databases, tables, materialized views, and schemas, see the Developer Experience ClickHouse databases catalog (internal only).
