secondary indexes

[Fernando Padilla <fe...@alum.mit.edu>]

Hi.  I have a very good use for a secondary index.. but I'm trying to 
find out some information ( pros, cons, performance, anything ), about 
them to validate my need for them. :)

But doing a google search I can only come across two blog posts, that 
show the how-to of using it, but do not have the details of 
pros/cons/performance of using secondary indexes.

Would anyone have any more links/docs for me to read? :) :)

thank you.
