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:

------------------------------------------------------------------------------
  I expect Hadoop + Hbase to handle sparsity and data explosion very well in near future.
  [[BR]]Moreover, i believe the design of the multi-dimensional structure and the 3-dim space
model of the data are [[BR]]optimized for rapid ad-hoc information retrieval in any orientation,
as well as for fast, flexible calculation and transformation of [[BR]]raw data based on formulaic
relationships.
  
- Then, I think it requires a user-friendly interface to enable querying the data interactive.

interactive. 
- [[BR]]So, I began building parallel processing shell to help make general algebraic and
logical data modeling works easier on Hadoop + Hbase
