SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Decide when to use warehouse-native UDFs vs dbt macros and provide a framework to implement, version, and govern them consistently across warehouses and models.

Core Features & Use Cases

  • Decision framework for macro vs UDF selection across warehouses.
  • Standardized governance: versioning, documentation, and adapter dispatch wrappers.
  • Practical patterns for implementing, wrapping, and deploying UDFs and macros across dbt projects.

Quick Start

Outline a representative SQL transformation you apply across multiple models and indicate whether to implement it as a UDF or a macro.

Frequently Asked Questions about warehouse-udf-strategy

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I decide between using a dbt macro and a warehouse UDF for repeating SQL transformations?▼

To decide between a dbt macro and a warehouse UDF, you evaluate tradeoffs in deterministic deployment, versioning, and cross-warehouse compatibility. This framework automates that selection based on your specific transformation logic and warehouse targets.

What is the best way to govern and version warehouse UDFs across multiple dbt projects?▼

The best way to govern warehouse UDFs across dbt projects is implementing standardized versioning, documentation, and adapter dispatch wrappers. This ensures consistent deployment and compatibility across different warehouse environments.

How do I maintain cross-warehouse compatibility when deploying SQL transformations with dbt?▼

You maintain cross-warehouse compatibility for SQL transformations by using adapter dispatch wrappers in dbt. This approach standardizes UDF implementation and ensures consistent logic execution across various warehouse platforms.

Can I use dbt macros to wrap warehouse-native UDFs for deterministic deployment?▼

Yes, you can use dbt macros as wrapper macros around warehouse-native UDFs. This pattern provides deterministic deployment and versioning while utilizing native warehouse execution performance for your SQL transformations.

When should I not use a warehouse-native UDF over a dbt macro?▼

You should avoid warehouse-native UDFs when your dbt project requires executing repeating transformation logic across many different warehouses. In these cases, dbt macros with adapter dispatch provide better cross-warehouse compatibility than native functions.

How do I start standardizing UDF and macro governance in my dbt project?▼

To start standardizing UDF and macro governance, outline a representative SQL transformation you apply across multiple models. This provides the baseline to determine whether a UDF or macro implementation best meets your versioning and deployment needs.
