With the growth of the Internet, and most successful web projects, it is increasingly necessary to use scalable databases capable of managing efficiently large volumes of information.
One case that we have mentioned is that of Cassandra DB, a distributed database open source that already use Digg, Facebook and Twitter.
Today I've discovered another promising project. This is Hypertable, another Open Source distributed data storage system that announces maximum performance and scalability to handle large amounts of data. Has commercial support at www.hypertable.com and search engines such as Baidu, Rediff.com or Zvents are already using it.
