MetricFlow

MetricFlow is a Python library (version 0.209.0) developed by dbt Labs that serves as the engine for defining, querying, and serving metrics from dbt projects. It translates high-level metric definitions into reusable SQL and executes them against various data platforms. While it powers the dbt Semantic Layer, direct programmatic API usage is primarily for advanced scenarios like custom metric servers or programmatic SQL generation, rather than typical application-level querying. Releases typically align with dbt Core release cycles or critical updates for MetricFlow's standalone capabilities.
