Subject [Lucene-hadoop Wiki] Trivial Update of "Hbase/ShellPlans" by stack
Date Wed, 08 Aug 2007 23:08:32 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 stack:

The comment on the change is:

   * A Simplified Parallel Numerical Analysis by abstracting/numericalizing points, lines,
or plane data across multiple maps in HBase.
   ''~-Does the import/export above include being able to write HQL/altool scripts feeding
them to the interpreter on stdin or passing the interpreter a file of script? It would be
sweet too if the interpreter could be invoked with a flag which stated how results were to
be output.  ACSII tables could be the default as it is now but users will likely want output
without formatting or output formatted as XML, etc.  Something to think about.  Also, Edward,
I'd suggest that you would be doing yourself a service if you added citations for concepts
like 'Parallel Numerical Analysis'.  It will help folks like myself does not know what this
means.  Thanks. -- St.Ack -~''
+ ''~-One other thing Edward.  What about JOINs?  How or where do you foresee these being
done?  Running a mapreduce job that read from two tables and wrote a third might make for
a simple start. -- St.Ack -~''
  === HBase altools Background ===
  I expect Hadoop + Hbase to handle sparsity and data explosion very well in near future.
Moreover, i believe the design of the multi-dimensional map structure and the 3d space model
of the data are optimized for rapid ad-hoc information retrieval in any orientation, as well
as for fast, flexible calculation and transformation of raw data based on formulaic relationships.
It is advantageous with respect to '''Analysis Processing'''  as it allows users to easily
formulate complex queries, and filter or slice data into meaningful subsets, among other things.
