Bigtable is a
compressed, high performance, and
proprietary data storage system built on
Google File System, Chubby Lock Service, SSTable (log-structured storage like
LevelDB) and a few other
Google technologies. On May 6, 2015, a public version of Bigtable was launched as
Google Cloud Bigtable. Bigtable also underlies Google Datastore, which is available as a part of the
Google Cloud Platform.
