Which project gives you a distributed, Scalable, data store that allows you random, realtime read/write access to hundreds of terabytes of data?Use Apache HBase when you need random, realtime read/write access to your Big Data. Note: 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, columnoriented store 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.FeaturesLinear and modular scalability.Strictly consistent reads and writes.Automatic and configurable sharding of tablesAutomatic 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 FiltersThrift gateway and a REST-ful Web service that supports XML, Protobuf, and binary data encoding optionsExtensible jruby-based (JIRB) shellSupport for exporting metrics via the Hadoop metrics subsystem to files or Ganglia; or via JMXReference: http://hbase.apache.org/ (when would I use HBase?
