Hypertable  Hypertable was an open-source software project to implement a database management system inspired by publications on the design of Google's Bigtable. Hypertable runs on top of a distributed file system such as the Apache HDFS, GlusterFS or the CloudStore Kosmos File System (KFS). It is written almost entirely in C++ as the developers believed it had significant performance advantages over Java. Hypertable software was originally developed at the company Zvents before 2008. Doug Judd was a promoter of Hypertable. In January 2009, Baidu, the Chinese language search engine, became a project sponsor. A version 0.9.2.1 was described in a blog in February, 2009. Development ended in March, 2016.
