Us too at SimpleGeo! We're Python, Cassandra, Erlang, and a smattering
of Java and C++.
We have offices in Boulder, CO and SF.

I don't know why it'd be very useful to be honest. Lots of us have CF's with
billions of keys. Ours,

The advantage of the random partitioner is that it randomly distributes your
keys across the cluster. This (theoretically) avoids key clustering on nodes.
The big disadvantage is that you can

I don't know of anyone off the top of my head who's using anything built on top
of Hadoop for a real-time environment. Hadoop just wasn't built

I'm assuming another alternative is to add more boxes to your cluster.

I believe you're limited by the amount of RAM on a machine (for now). So if
you've given the JVM 8GB then a single SuperColumn can't be more than 8GB.

SimpleGeo is using Cassandra as the backend of our real-time location
infrastructure. We needed something that was distributed, could scale,
could handle lots of writes, etc.
We looked into all the usual suspects, but went with Cassandra because
it was written in Java (we have two guys who

I'll continue to object to this. If you're considering running
Cassandra (or MySQL or Reddis or Memcache or MemcacheDB or ...) on an
open network Ur Doin' It Wrong. This is what VP
SimpleGeo would be interested.

Hey,
At Digg we've been thinking about counters in Cassandra. In a lot of
our use cases we need this type of support from a distributed
storage system. Anyone else out there who has such needs as well?
As I said in my email, it's a code test. Simply meant to test an
applicant's skills during the hiring process.
I'm aware of OPP and COPP and choosing partitioners.

For click tracking data I might look at Hadoop as well. It can handle
the writes, replication, etc. along with being mechanisms for
crunching large datasets built in (e.g. MapReduce).
That being said, you're working with data that, for the most part, it
won't be the end of the world if you

Sure. SOLR is kind of like this for Lucene.

I'm strongly against ACL. Cassandra was built for highly scalable and
highly distributed environments, which always sit behind firewalls.
ALC's can easily be implemented in a service layer in front of
Cassandra.

I'd recommend still using Memcached for sessions. The reason is
because Memcached has built in garbage collection of zombie sessions
(via LRU) and Cassandra does not.

It only works with 0.3. There are people making progress to get it
