server needs thrift to run also?
I'm trying to follow along the twissandra installation instructions.
So to get it running I have to install Thrift.
So thrift runs as another service? So communication is done via thrift,
which then communicates to Cassandra on another port?

I'll take a guess.
S Ahmed, the Thrift compiler takes a .thrift file and can generate client
and server code for it in your language of choice. This code depends on the
Thrift runtime library in that language.
For instance, the Thrift Java runtime library is bundled with Cassandra as a
jar. When developers want to change the interface, they change the .thrift
file and generate server code from it. This code is also then bundled with
Cassandra, and depends on the jar.
Twissandra includes pycassa, which has already generated the client code
from the .thrift file for you. You don't need to generate any code. You
do, however, need to install the Thrift Python runtime library.

You were just told it is packaged with what it needs. The API is not
changed from 0.6.1 to 0.6.3. Why do you think you need to generate
client code?

I think it would do that already, assuming that pycassa itself was
installable from the cheeseshop (not sure why it isn't). Twissandra is
actually using an embedded copy of pycassa.

Pretty much, but you do need to install the Thrift python module (which
the README does say).
Try: easy_install thrift
If you don't have easy_install, download and run:
http://peak.telecommunity.com/dist/ez_setup.py
... and then try again.

You don't need to generate any code.

Ok I guess I have to read up on exactly what is going on here.
I figured I could download twissandra, fire up cassandra and run the app!
I thought all you needed was the python driver which comes with twissandra.
Let me read more about Thrift and generating client code etc.
thanks!

Twissandra is packaged with pycassa + correct generated thrift
transports under /deps already, so really just need the thrift binary
to build from a cassandra.thrift API newer than what's currently
supported by the bundled pycassa.

You'll need Thrift installed to generate the _client_ code: the server code is embedded within Cassandra.

The Thrift server is embedded in Cassandra, and starts by default. Look for references to Thrift on: http://wiki.apache.org/cassandra/GettingStarted

I'm trying to follow along the twissandra installation instructions.
So to get it running I have to install Thrift.
So thrift runs as another service? So communication is done via thrift,
which then communicates to Cassandra on another port?
