it would be nice to have a more comprehensive deployment guide.
You're right. Maybe we can get Digg to share theirs. :)
We don't have any such thing. The deployment at Digg is just as alpha as
the deployment anywhere

We're using Cassandra in development to store custom index information
on large document sets. Also considered HBase and Voldemort.
Cassandra's data model and performance tradeoffs seemed to best fit
our needs.
Features that we're looking forward to seeing:
* map/reduce integration

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
Hello, I'm working at bee.tv. We build actually a large application related
to smart TV and movies recommendations.
We've developed an application wich was only based on Oracle + Java server
side but it was not enough scalable solution. Of course Oracle have
capabilities to scale but you need to
Hi Jonathon,
I'd say I am at the evaluation stage. The only reason I am looking at nosql
type applications instead of using mysql is the vain hope my application
will one day scale to the point that mysql won't be the best option.
Cassandra appears to be the best fit for the requirement I have
Hi,
I'm using Cassandra 0.4.2 at my current client to persist URL graphs
for Spam detection.
The crawling and page classification is done in Hadoop/Bixo/Cascading,
which persists URL classification results into Cassandra.
The incoming production traffic is using Cassandra for the real-time
spam
The company I'm with is still small and in the early stages, but we're
planning on using Cassandra for user profile information (in
development right now), and possibly other uses later on. We
evaluated CouchDB and Voldermort, and both of those were great as well
- for CouchDB, I really liked
I am evaluating NoSQL alternatives to your typical hard to scale
RDBMS, specifically Key/Value stores. I'm not looking for query
capabilities. I want very very very high availability with very very
large amounts of data.
I have reduced down my list to Cassandra, Voldemort, Riak, and CouchDB.
We are currently evaluating Cassandra, and using it for a small
feature in production. We are only using the basic insert/get/remove
from the API, with a standard column family. So far, I like a lot of
what Cassandra offers, though I had some tough times with it.

At twitter we're working on using Cassandra to replace our currents
storage for all tweets. We have a cluster in production that's being

We're looking at it to be part of a near real time Web analytics engine, which
sounds similar to Ooyala.
at the moment I'm pushing to get the thing open sourced if possible.
we're looking at combining Cassandra + Esper, but we are still in the very
early stages.

For a project I am working on now at Onespot we are just beginning to move
off RDBMS and onto Cassandra for a subset of our data store. We evaluated
against several other solutions including Tokyo, Voldemort and Riak and
Cassandra seemed the clear winner for our requirements. We have also done
I'm about to release a twitter search engine built ontop of cassandra. If

I would like to see cassandra support increment/decrement.
