An Inside Look at Google BigQuery

This white paper introduces Google BigQuery, a fully-managed and cloudbased interactive query service for massive datasets. BigQuery is the external
implementation of one of the company’s core technologies whose code name
is Dremel. This paper discusses the uniqueness of the technology as a cloudenabled massively parallel query engine, the differences between BigQuery
and Dremel, and how BigQuery compares with other technologies such as
MapReduce/Hadoop and existing data warehouse solutions.
