Re: HBase Analytics: A New DB for 80% of Facebook, YouTube-scale Sites

[Andrew Purtell <ap...@apache.org>]

I agree. Well done!

You may also want to look at how Vertica implements parallel analytics on
top of a column based store commercially:
  http://www.vertica.com/_pdf/VerticaArchitectureWhitePaper.pdf

For example, this is interesting:

  "Logical tables are decomposed and physically stored as overlapping
   groups of columns, called "projections," and each projection is sorted
   on a different attribute (or set of attributes), which optimizes them
   for answering queries with predicates on its sort attributes."

Call that insert-time view materialization? 

Clint Morgan's THBase contrib is maybe the first step down the road to
something like that done with an eager strategy. A lazy approach could do
something in the background whenever a WAL is rolled.
