We use the python-driver and have contributed some to its development.
I have been careful to not push too fast on features until we need them.
For example, we have just started using prepared statements - working well
BTW.
Next we will employ futures and start to exploit the async nature of new
Michael - thanks. Have you tried batching and thread pooling in python-driver?
For now, i would avoid object mapper cqlengine, just because of my deadlines.

Jon - Thanks. As I understand, cqlengine is an object mapper and must be using
for cql prepare statements. What are you wrapping it with, in alternative to
python-driver?

We're currently using the cql package, which is really a wrapper around
thrift.
To your concern about deadlines, I'm not sure how writing raw CQL is going
to be any faster than using a mapper library for anything other than the
most trivial of project.

I think thread pooling is always in operation - and we haven't seen any
problems in that regard going to the 6 local nodes each client connects to.
We haven't tried batching yet.

Hi Jon - you are right. Its that I understand other ORM like python sqlalchemy
or perl DBIX by heart. So i can cql faster than use cqlengine. I will give a
shot at python-driver based on Michael's recommendation.

I would take a look at pycassa - https://github.com/pycassa/pycassa though
there is also a twisted client named Telephus -

Guys,
I just installed python-cassandra 0.6.1 and Thrift 0.5.0 on my machine and I
would like to query against also write into a cassandra server. I guess i
am pretty weak in google-fu, there isn't any examples for me get started
with. Please help me on how to do this.
Thanks,

Right, python-cassandra just provides the raw Thrift API, which is no fun at
all. You should start out with pycassa.

That’s pretty impressive to me. I also later confirmed that with multiple
nodes the query across multiple keys is much faster. Also using a clientpool
would probably speed it up more too.
Then I ran a python client
It does not have a c extension as far as I know
