Subject Re: geocouch with 3rd dimension
Date Tue, 05 Jun 2012 09:20:07 GMT
You could use couchdb-lucene to do an N dimensional query. Filtering stuff out in a list is
generally not very efficient because the result isn't cached for subsequent queries, and if
your filter is sparse you may find queries are slow as you do a lot of work before being able
to respond to the client. 
Cheers
Simon

the only option? Since this means touching every record in the result set, are there any performance
implications?
