Concept
BigQuery
Summary
BigQuery is Google's fully managed, serverless data warehouse that enables scalable analysis over petabytes of data. It is a Platform as a Service (PaaS) that supports querying using a dialect of SQL. It also has built-in machine learning capabilities. BigQuery was announced in May 2010 and made generally available in November 2011.
BigQuery provides external access to Google's Dremel technology, a scalable, interactive ad hoc query system for analysis of nested data. BigQuery requires all requests to be authenticated, supporting a number of Google-proprietary mechanisms as well as OAuth.
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 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.
Integration - BigQuery can be used from Google Apps Script (e.g. as a bound script in Google Docs), or any language that can work with its REST API or client libraries.
Access control - Share datasets with arbitrary individuals, groups, or the world.
Machine learning - Create and execute machine learning models using SQL queries.
Cross-cloud analytics - Analyze data across Google Cloud, Amazon Web Services, and Microsoft Azure
Data sharing - Exchange data and analytics assets across organizational boundaries.
In-Memory analysis service - BI Engine built into BigQuery that enables users to analyze large and complex datasets interactively with sub-second query response time and high concurrency.
Business intelligence - Visualize data from BigQuery by importing into Data Studio, a data visualization tool
The two main components of BigQuery pricing are the cost to process queries and the cost to store data. BigQuery offers two types of pricing - on demand pricing which charges for the number of petabytes processed for each query and flat-rate pricing which charges for slots or virtual CPUs.
