Hi,
What is most efficient way to retrieve a row when the value of a certain
column is specified ( rather than the row key ) ?
Thanks in advance
Thanx Bryan for the quick response !
My table is very sparse and contains 100 column families , each containing
about 20 items. Also, I need to search the table by each of the columns so
the solution you suggested seems somewhat complicated for this purpose.
So my ensuing questions are :
1. Do
Right now, we don't have a plan to add indexing. It's a particularly
complicated area of functionality. We'd love to get suggestions (or
patches :) for how to do this the right way.
Map/reduce would be the perfect way to find all records that matched
on a column value, so long as you're
Hi Shimon,
You may also want to look into a text indexing solution such as Lucene
or Ferret. These systems might be able to provide the search
capabilities you require. Of course, it'd be your responsibility to
keep the indexes up to date.

When the application creates an entity, it can assign another entity as the
parent of the new entity. Assigning a parent to a new entity puts the new
entity in the same entity group as the parent entity.
I think I need to sign up for app engine and use it to see if I can figure

He's saying that if you're going to be searching for one random thing
at a time, and you want it to be /fast/, then issuing a full table
scan to a hadoop cluster as a map/reduce job is not a good solution.
It's not really practical to send out a swarm of nodes hunting through
your whole dataset
Hello
i checkout hbase from trunk and i see that there is new version of the
hbase shell. i see in comments that it base on jruby..., but how can i
use it ? unfortunatelly old shell has been removed.
Best regards - Antony
Shell support is in a state of flux at the moment.
Meantime, your only avenue is typing ruby at the proffered irb prompt.
See this page for example code: http://wiki.apache.org/hadoop/Hbase/JRuby
