Research direction
Start by examining the referenced file `packages/cubejs schema compiler/src/scaffolding/ScaffoldingSchema.js` at line 144. Investigate how the schema generator infers column types and why it defaults to string. Look for any type mapping functions or data type detection logic. Check if there are existing tests for schema generation in the same package to understand expected behavior. Review comments in the issue for any additional insights or proposed fixes.
