| <section name="Welcome to Apache HBase™"> |
| <p><a href="http://www.apache.org/">Apache</a> HBase™ is the <a href="http://hadoop.apache.org">Hadoop</a> database, a distributed, scalable, big data store. |
| </p> |
| <h4>When Would I Use Apache HBase?</h4> |
| <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 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> |
| <h4>Features</h4> |
| <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> |
| </p> |
| <h4>Where Can I Get More Information?</h4> |
| <p>See the <a href="http://hbase.apache.org/book/architecture.html#arch.overview">Architecture Overview</a>, the <a href="http://hbase.apache.org/book/faq.html">Apache HBase Reference Guide FAQ</a>, |
| and the other documentation links on the left! |
| </p> |
| <h4>Export Control</h4> |
| <p>The HBase distribution includes cryptographic software. See the export control notice <a href="export_control.html">here</a> |
