BigTable
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.〔http://googlecloudplatform.blogspot.com/2015/05/introducing-Google-Cloud-Bigtable.html〕 Bigtable also underlies Google Datastore,〔http://googledevelopers.blogspot.com/2013/05/get-started-with-google-cloud-datastore.html〕 which is available as a part of the Google Cloud Platform. ==History== Bigtable development began in 2004〔.〕 and is now used by a number of Google applications, such as web indexing,〔.〕 MapReduce, which is often used for generating and modifying data stored in Bigtable, Google Maps,〔.〕 Google Book Search, "My Search History", Google Earth, Blogger.com, Google Code hosting, YouTube,〔.〕 and Gmail.〔.〕 Google's reasons for developing its own database include scalability and better control of performance characteristics. Google's Spanner RDBMS is layered on an implementation of Bigtable with a Paxos group for two-phase commits to each table. Google F1 was built using Spanner to replace an implementation based on MySQL.〔.〕
