pypreqlt 0.0.1

Enhanced PreQL for common ETL needs.

Simple Data Pipelines

Combine the simplicity and guarantees of Preql with the power of open source ETL.

Compile your models to ETL scripts to run on demand through the modern data stack. Rebuild on demand.

Currently supported backends:

• DBT

Flags

--optimize=X - Any CTE used at least X times in calculating final model outputs will be materialized for reuse.

Install

pip install pypreqlt

How to run

Copy example_file contents into models\example for the "jaffle_project" DBT starter
