This library supports Python version 3.7+ and meant to provide tools for building ETL pipelines for Feature Stores using Apache Spark.

The library is centered on the following concetps:

  • ETL: central framework to create data pipelines. Spark-based Extract, Transform and Load modules ready to use.
  • Declarative Feature Engineering: care about what you want to compute and not how to code it.
  • Feature Store Modeling: the library easily provides everything you need to process and load data to your Feature Store.

To understand the main concepts of Feature Store modeling and library main features you can check Butterfree's Documentation, which is hosted by Read the Docs.
