dbt Performance Optimization FAQs

Question 1

How does this skill improve my development workflow?

Accepted Answer

It speeds up your workflow by automating performance analysis. Instead of manually reviewing query profiles, you can use Claude to calculate optimal warehouse sizes using the '500 micropartitions per node' formula and identify specific SQL anti-patterns like functions on join columns.

Question 2

What does the dbt Performance Optimization skill do?

Accepted Answer

This skill equips Claude Code with deep technical knowledge of dbt and Snowflake performance. It enables the AI to provide expert guidance on selecting materializations, sizing warehouses based on micropartition metrics, and implementing advanced SQL patterns for faster data transformations.

Question 3

Can this skill help with SQL query optimization?

Accepted Answer

Yes. It provides optimized query patterns such as using the QUALIFY clause for window functions, 'filter-before-join' logic to reduce memory pressure, and best practices for writing efficient WHERE clauses in incremental models to ensure proper partition pruning.

Question 4

When should I use this skill in my dbt project?

Accepted Answer

Activate this skill when you encounter slow-running models, memory constraints, or high Snowflake compute costs. It is ideal for transitioning models from table to incremental materializations, setting up clustering keys, or troubleshooting complex query bottlenecks.

Question 5

What specific Snowflake features does this skill support?

Accepted Answer

The skill provides specialized guidance on Snowflake-specific optimizations including Gen2 Standard Warehouses, Search Optimization Services, Clustering Keys, Query Acceleration, and effective result caching strategies to minimize compute usage.
