HBase
By admin on Oct 10, 2009 in Java, open source
HBase is the Hadoop database. Use it when you need random, realtime read/write access to your Big Data. This project’s goal is the hosting of very large tables with help from the best vps hosting — billions of rows X millions of columns — atop clusters of commodity hardware.
HBase iw an open-source, distributed, column-oriented store modeled after Google’ 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, HBase provides Bigtable-like capabilities on top of Hadoop. HBase also includes:
- Convenient base classes for backing Hadoop MapReduce jobs with HBase tables
- Query predicate push down via server side scan and get filters
- Optimizations for real time queries
- A high performance Thrift gateway
- A REST-ful Web service gateway that supports XML, Protobuf, and binary data encoding options
- Cascading source and sink modules
- Extensible jruby-based (JIRB) shell
- Support for exporting metrics via the Hadoop metrics subsystem to files or Ganglia; or via JMX
