Overview#
BigQuery is a RESTful web service that enables interactive analysis of massively large datasets working in conjunction with Google Cloud Storage and is Infrastructure as a Service (IaaS) that may be used complementarily with MapReduce.[1]BigQuery is fully managed, petabyte scale, low cost enterprise data warehouse for analytics. BigQuery is serverless. [2]
BigQuery provides an external access to the Dremel technology, a scalable, interactive Ad Hoc query system for analysis of readOnly nested data.
BigQuery requires the data be uploaded to Google Cloud Storage and in a second step imported using the BigQuery HTTP API.
BigQuery requires all requests to be authenticated, supporting a number of Google-proprietary mechanisms as well as OAuth 2.0.
BigQuery queries are expressed in a standard SQL dialect and the results are returned in JSON.
