Hypertable is a high performance, open source, massively scalable database modeled after Bigtable, Google's proprietary, massively scalable database. 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.
As is the case with all databases, there are certain circumstances when Hypertable can get into an inconsistent state.
Hypertable provides a number of diagnostic and recovery tools that can be used to get Hypertable back into a consistent and operational state.
These tools include HTCK, LOG_PLAYER, METALOG_TOOL, and SALVAGE.
