From STTM to Snowflake SQL: Building a Metadata-Driven Data Engineering Copilot

Most data engineering teams do not struggle because they lack smart people.

They struggle because too much of the delivery process is still repetitive.

A source-to-target mapping document comes in.

Then someone has to manually create:

• target table DDL
• transformation SQL
• data dictionary
• technical specification
• data quality rules
• reconciliation checks
• test cases

For one or two tables, this is manageable.

For a real enterprise program with many tables, changing requirements, multiple source systems, and repeated delivery cycles, this becomes a major productivity problem.

That is the problem I am exploring with Data Engineering Copilot.
