| </div> |
| <p><a class="externalLink" href="http://www.apache.org/">Apache</a> HBase™ is the <a class="externalLink" href="http://hadoop.apache.org">Hadoop</a> database, a distributed, scalable, big data store. </p> |
| <div class="section"> |
| <div class="section"> |

| <h4 id="When_Would_I_Use_Apache_HBase">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 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> |
| </div> |
| <div class="section"> |
| <h4 id="Features">Features</h4> |
| <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> |
