Subject [Lucene-hadoop Wiki] Trivial Update of "Hbase/ShellPlans" by udanax
Date Sun, 19 Aug 2007 00:23:01 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Lucene-hadoop Wiki" for change notification.

The following page has been changed by udanax:
http://wiki.apache.org/lucene-hadoop/Hbase/ShellPlans

------------------------------------------------------------------------------
  = Hbase Shell Plan Draft =
  Plan is to significantly expand the set of shell operators.  Basic data manipulation and
data definition operators will be extended and evolved to be more SQL-like ([wiki:Hbase/HbaseShell/HQL
HQL]).  More sophisticated manipulations to do relational and linear algebra, matrix additions,
multiplications, etc., will be added to a HBase subshell to keep the two operator types --
SQL-like vs. non-SQL -- distinct.

HADOOP-1608] to add "Relational Algrebra Operators" is currently in process.

data processing capabilities like  aggregation, algebraic calculation(groups and sets, commutative
rings, algebraic geometry, and linear algebra) on Hadoop + Hbase based parallel machines.
especially, it will focus on storing and manipulating sparse matrices on Hbase.
