BigFunctions is an open-source framework for creating and managing a catalog of BigQuery functions. It offers over 100 ready-to-use functions, enabling users to enhance their BigQuery data analysis. The framework caters to various roles, from data analysts to data engineers, streamlining workflows and promoting best practices. A command-line interface (CLI) simplifies function deployment, testing, and management, and the project encourages community contributions. The functions can be called directly or deployed within a user's GCP project.
