HBase is an open source, non-relational, distributed database modeled after Google's BigTable and is written in Java. It is developed as part of Apache Software Foundation's Apache Hadoop project and runs on top of HDFS (Hadoop Distributed Filesystem), providing BigTable-like capabilities for Hadoop. That is, it provides a fault-tolerant way of storing large quantities of sparse[clarification needed] data.
HBase features compression, in-memory operation, and Bloom filters on a per-column basis as outlined in the original BigTable paper.[1] Tables in HBase can serve as the input and output for MapReduce jobs run in Hadoop, and may be accessed through the Java API but also through REST, Avro or Thrift gateway APIs.
HBase is not a direct replacement for a classic SQL database, although recently its performance has improved, and it is now serving several data-driven websites,[2][3] including Facebook's Messaging Platform.[4][5]
In the parlance of Eric Brewer’s CAP theorem, HBase is a CP type system.

History [edit]
Apache HBase began as a project by the company Powerset out of a need to process massive amounts of data for the purposes of natural language search. It is now a top-level Apache project and has generated considerable interest.[6]
Facebook elected to implement its new messaging platform using HBase in November 2010.[4]
