Google's distributed wide-column database, and the ancestor of half the NoSQL world.
The 2006 paper described a sparse, sorted, multi-dimensional map indexed by row key, column and timestamp. Built on GFS and Chubby, with SSTable files and LSM trees underneath. It ran internally behind Search, Maps, Gmail and Analytics.
Apache HBase is a direct open reimplementation, and Cassandra borrowed the data model (taking its consensus design from Dynamo instead). Since 2015 the original has been sold as Cloud Bigtable.
