Hypertable is an open sourcedatabase system inspired by publications on the design of Google's BigTable. The project is based on experience of engineers who were solving large-scale data-intensive tasks for many years.
Hypertable runs on top of a distributed file system such as the Apache HDFS, GlusterFS or the Kosmos File System (KFS). It is written almost entirely in C++ as the developers believe it has significant performance advantages over Java.
