href="http://hadoop.apache.org/">Hadoop</a> database, a distributed, scalable, big data store. </p> <p>Use Apache HBase™ when you need random, realtime read/write access to your Big Data. This project's goal is the hosting of very large tables -- billions of rows X millions of columns -- atop clusters of commodity hardware. Apache HBase is an open-source, distributed, versioned, non-relational database modeled after Google's <a class="externalLink" href="http://research.google.com/archive/bigtable.html">Bigtable: A Distributed Storage System for Structured Data</a> by Chang et al. Just as Bigtable leverages the distributed data storage provided by the Google File System, Apache HBase provides Bigtable-like capabilities on top of Hadoop and HDFS. </p> </section> <section> <h2><a name="Download"></a>Download</h2> <p> Click <b><a class="externalLink" href="http://www.apache.org/dyn/closer.cgi/hbase/">here</a></b> to download Apache HBase™. </p> </section> <section> <h2><a name="Features"></a>Features</h2> <p> </p> <ul> <li>Linear and modular scalability. </li> <li>Strictly consistent reads and writes. </li> <li>Automatic and configurable sharding of tables </li> <li>Automatic failover support between RegionServers. </li> <li>Convenient base classes for backing Hadoop MapReduce jobs with Apache HBase tables. </li> <li>Easy to use Java API for client access. </li> <li>Block cache and Bloom Filters for real-time queries. </li> <li>Query predicate push down via server side Filters </li> <li>Thrift gateway and a REST-ful Web service that supports XML, Protobuf, and binary data encoding options </li> <li>Extensible jruby-based (JIRB) shell </li> <li>Support for exporting metrics via the Hadoop metrics subsystem to files or Ganglia; or via JMX </li> </ul> </section> <section> <h2><a name="More_Info"></a>More Info</h2> <p>See the <a class="externalLink" href="http://hbase.apache.org/book.html#arch.overview">Architecture Overview</a>, the <a class="externalLink" href="http://hbase.apache.org/book.html#faq">Apache HBase Reference Guide FAQ</a>, and the other documentation links. </p> <dl> <dt>Export Control</dt> <dd> <p>The HBase distribution includes cryptographic software.
