Hadoop database, a distributed, scalable, big data store

Apache HBase is an open-source, distributed, versioned, non-relational database modeled after Google’s Bigtable A Distributed Storage System for Structured Data 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.

Features – Linear and modular scalability – Strictly consistent reads and writes – Automatic and configurable sharding of tables – Automatic failover support between RegionServers – Convenient base classes for backing Hadoop MapReduce jobs with Apache HBase tables – Easy to use Java API for client access – Block cache and Bloom Filters for real-time queries – Query predicate push down via server side Filters – Thrift gateway and a REST-ful Web service that supports XML, Protobuf and binary data encoding options – Extensible jruby-based JIRB shell – Support for exporting metrics via the Hadoop metrics subsystem to files or Ganglia, or via JMX
