Subject Re: Cassandra users survey
Date Sat, 21 Nov 2009 18:00:30 GMT
Hi Jonathan,

Firstly, thanks for all your help on this list. Without lots of your
solutions / tips etc I probably wouldn't be using Cassandra.

I've built a real-time search engine based around all the links that appear
on twitter (http://www.mozzler.com/). Cassandra is my data store for all the
comments associated with a link, mapping short URL's to endpoint URL's etc.
Cassandra is also used for session and user data for the web front end, in
conjunction with memcached to speed up the writes.

If anyone wants a simple django session manager that uses lazyboy to talk to
cassandra, let me know.

Cheers,
Chris
