30 <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.
32 <p>Use Apache HBase™ when you need random, realtime read/write access to your Big Data.
33 This project's goal is the hosting of very large tables -- billions of rows X millions of columns -- atop clusters of commodity hardware.
34 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.
35 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.

58 <li>Block cache and Bloom Filters for real-time queries.
60 <li>Query predicate push down via server side Filters
62 <li>Thrift gateway and a REST-ful Web service that supports XML, Protobuf, and binary data encoding options
64 <li>Extensible jruby-based (JIRB) shell
66 <li>Support for exporting metrics via the Hadoop metrics subsystem to files or Ganglia; or via JMX
