Apr 1, 2025Month: 2025-04. Delivered a major enhancement to the cube-js/cube Schema Compiler: it now generates SQL for joins using dimension references where possible, improving efficiency and readability of generated schema files. Key changes include the addition of a notEmpty helper and refactors of ScaffoldingSchema and BaseSchemaFormatter to support the new join SQL generation strategy. Updated tests and linting accompany the change to ensure reliability and code quality. Commit reference: 8fc4f7c4125889fcc24306256665d61ac30198c3.
