HBASE hadoop database really new features to handle growing data volumes

Hbase is Java implementation of Google's Big Table. The Data in HBASE stores as two parts.
hadoop hbase
Row Key : 00001 
Column : (Column Qualifier:Version:Value)

Features of HBASE

  • HBase data stores consist of one or more tables, which are indexed by row keys.
  • Data is stored in rows with columns, and rows can have multiple versions.
  • By default, data versioning for rows is implemented with time stamps.
  • Columns are grouped into column families, which must be defined up front during table creation. Column families are stored together on disk, which is why HBase is referred to as a column-oriented data store

In addition...

HBASE is a distributed data store, which leverages a network attached cluster of low-cost commodity servers to store and persist data.HBASE architecture is a little trick to know.

Region Servers...

RegionServers are the software processes (often called daemons) you activate to store and retrieve data in HBase.

The big difference...

  • HABSE handles growing data or big data. HBase automatically scales as you add data to the system. A huge benefit compared to most database management systems, which require manual intervention to scale the overall system beyond a single server. 
  • With HBase, as long as you have in the rack another spare server that's configured, scaling is automatic.
