Google BigQuery Python Samples
===============================================================================

This directory contains samples for Google BigQuery. `Google BigQuery`_ is Google's fully managed, petabyte scale, low cost analytics data warehouse. BigQuery is NoOps—there is no infrastructure to manage and you don't need a database administrator—so you can focus on analyzing data to find meaningful insights, use familiar SQL, and take advantage of our pay-as-you-go model.
.. _Google BigQuery: https://cloud.google.com/bigquery/docs
To run the sample, you need to have the `BigQuery Admin` role.
