Summary
This PR introduces a new endpoint
/sql/measures/v3/combinedthat generates SQL combining multiple grain groups into a single query usingFULL OUTER JOIN. This enables efficient materialization of pre-aggregated data from multiple fact tables into a single combined table.When building Druid cubes or similar OLAP materialization pipelines, it's often necessary to combine metrics from different fact tables (e.g., orders and page views) into a single pre-aggregated table.
