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:

• Dashboards - Pre-built dashboards for common use cases
  • System Tables - Looker Studio Dashboards built on BigQuery’s INFORMATION_SCHEMA metadata views to understand organization’s slot and reservation utilization, job execution, and job errors.
• Notebooks - Colab notebooks for various BigQuery related use cases.
  • BigQuery Frequent Items Sketches Demo - Calculating TopN file extensions in Git repos from public Github Dataset.
  • BigQuery KLL Sketches Demo - Calculating Quantiles over user defined time-windows.
  • BigQuery Theta Sketches Demo - Calculating Distinct User Logins over different months.
  • Geospatial - Colab notebooks for Geospatial Analytics.
• Performance Testing - Examples for doing performance testing
  • JMeter - Examples for using JMeter to test BigQuery performance
• Scripts - Python, Shell, & SQL scripts
  • billing - Example queries over the GCP billing
    export
  • optimization - Scripts to help identify areas for optimization in your BigQuery warehouse.
• Stored Procedures - Example stored procedures
• Third Party - Relevant third party libraries for BigQuery
  • compilerworks - BigQuery UDFs which mimic the behavior of proprietary functions in other databases
• Tools - Custom tooling for working with BigQuery
  • Cloud Functions - Cloud Functions to automate common use cases
• UDFs - User-defined functions for common usage as well as migration
  • community - Community contributed user-defined
    functions
  • datasketches - UDFs deployed from the latest release of Apache Datasketches for BigQuery
  • migration - UDFs which mimic the behavior of
    proprietary functions in the following databases:
    • netezza
    • oracle
    • redshift
    • snowflake
    • teradata
    • vertica
    • sqlserver
• 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).
