What are SQLMesh virtual environments?

Virtual environments allow you to create isolated previews of your data changes. This skill helps you use the 'sqlmesh plan' command to test transformations in dev before promoting them to prod.

How does this skill handle data quality?

The skill includes patterns for defining SQLMesh audits, which allow you to verify data integrity (like checking for nulls or unique keys) as part of your transformation workflow.

What is the primary benefit of using SQLMesh with Claude Code?

SQLMesh provides a robust framework for data transformation that emphasizes correctness and efficiency. Using this skill, Claude can help you build pipelines with automatic dependency tracking and safe testing environments.

Can I use this for incremental data loading?

Yes, it provides specific implementation patterns for incremental models, allowing you to process only new data by time range or unique key, which saves time and compute costs.
