Hi all, I would like to propose introducing "The metrics & semantic modeling in Spark".
This feature enables defining business metrics once and reusing them across any breakdown, ensuring consistent outcomes and bridging the semantic gap between business logic and data schemas to help LLMs generate more precise results. Looking forward to your feedback!
