Getting Started

This repository is broken up into:

  • Scripts - Python, Shell, & SQL scripts
    • billing - Example queries over the GCP billing export
  • UDFs - User-defined functions for common usage as well as migration
    • community - Community contributed user-defined functions
    • teradata - UDFs which mimic the behavior of proprietary functions in Teradata
  • Views - Views over system tables such as audit logs or the INFORMATION_SCHEMA
    • query_audit - View to simplify querying the audit logs which can be used to power dashboards (example).

Public UDFs

All UDFs within this repository will be automatically created under the bqutil project under publicly shared datasets. Queries can then reference the shared UDFs via bqutil.<dataset>.<function>().
