Apache HBase is used when you need random, realtime read/write access to your Big Data.  Apache HBase hosts very large tables -- billions of rows X millions of columns -- atop clusters of commodity hardware. Apache HBase is a 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.

Detailed Description

Apache HBase is used when you need random, realtime read/write access to your Big Data. Apache HBase hosts very large tables -- billions of rows X millions of columns -- atop clusters of commodity hardware. Apache HBase is a 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.

Benefit to Fedora
