BigQuery Utils

BigQuery is a serverless, highly-scalable, and cost-effective cloud data warehouse with an in-memory BI Engine and machine learning built in. This repository provides useful utilities to assist you in migration and usage of BigQuery.

Getting Started

This repository is broken up into:

• Scripts - Python, Shell, & SQL scripts
  • billing - Example queries over the GCP billing export
• Stored Procedures - Example stored procedures
• UDFs - User-defined functions for common usage as well as migration
  • community - Community contributed user-defined functions
  • migration - UDFs which mimic the behavior of proprietary functions in the following databases:
    • netezza
    • oracle
    • redshift
    • teradata
    • vertica
• 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).
