An Inside Look at Google BigQuery

This white paper introduces Google BigQuery, a fully-managed and cloud based 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

Note: This is from 2012, so doesn’t include a lot of recent innovations like upsert and standard sql support.
