History
Bigquery originated from Google's internal Dremel technology,[2][3] which enabled quick queries across trillions of rows of data.[4] The product was originally announced in May 2010 at Google I/O.[5] Initially, it was only usable by a limited number of external early adopters due to limitations on the API.[4] However, after the product proved its potential, it was released for limited availability in 2011 and general availability in 2012.[4] After general availability, BigQuery found success among a broad range of customers, including airlines, insurance, and retail organizations.

Design
BigQuery requires all requests to be authenticated, supporting a number of Google-proprietary mechanisms as well as OAuth.
Features
- Managing data - Create and delete objects such as tables, views, and user defined functions. Import data from Google Storage in formats such as CSV, Parquet, Avro or JSON.
- Query - Queries are expressed in a SQL dialect[6] and the results are returned in JSON with a maximum reply length of approximately 128 MB, or an unlimited size when large query results are enabled.[7]
- Integration - BigQuery can be used from Google Apps Script[8] (e.g. as a bound script in Google Docs), or any language that can work with its REST API or client libraries.[9]
- Access control - Share datasets with arbitrary individuals, groups, or the world.
- Machine learning - Create and execute machine learning models using SQL queries.
