Description

Hey folks 👋 !

Is your feature request related to a problem? Please describe. As a cube JS user, i am frustrated not being able to confront my cube definition vs actual tables layout in database

Describe the solution you'd like Ideally, a CLI command npx cube-js validate-table-layout would generate 1 SQL query per cube and 1 SQL query per view then dry run (Where 1=2) it against a given database to check column existence

Describe alternatives you've considered I considered to build my own validation using a python script but it's cumberstone and would not benefit cube nor the comunity

Additional context Such feature exist for Looker for example

Contributor guide

Research direction
Investigate how cube js connects to databases and explore the possibility of running dry run SQL queries to validate column existence. Look at existing schema definitions and how to generate SQL from them.
