Hbase
Introduction
Hbase is one of the
component of hadoop built on top of HDFS and is ment for Real time
random read/write. In against to the sequential file accessing of
HDFS.
Hbase is opensource
, distributed, scalable , fault tolerance , non -relational,
multi-dimensional versioned, column oriented database which is built
on top of BIG TABLES (BUILT ON THE ORIGIN OF GFS).
Google big tables
ment for structured data only.
All the database
will be organized by the means of tables only and whenever we
inserting values in Hbase table for each and every values there will
be a unique timestamp which will be generated by HBASE TABLES
automatically.
HBASE is not a [part
of default installatipon of hadoop and hence therefore we need to
install it on top of hadoop only.
IN SVN when we
insert data and from other location B modified it it creates version.
