Thanks Jonathan.
But I made changes to sync_cassandra.py file there to include the
supercolumn. However looks like that has been the issue. I am not doing
something right there.

Most of the high level clients do this for you.
For example, pycassa and phpcassa both do this by returning an
iterator from get_range() and breaking it up behind the scenes.
Hector also has something similar, but I think it's in the examples
section.
What client are you using?

couple of weeks ago, I have written a post to summarize the information
that was made available. Thanks to Peter Schuller for helping clarifying
many issues. The post is available at:

Twissandra doesn't use supercolumns.

It's a compatibility bug in b3. Moving all the nodes to b3 will fix
it, or upgrading the new ones to 0.7 branch instead of b3 will too.

Hello,
I would like one of the cluster's nodes to use get_range_slices() to
retrieve the values of a specific column for the entire keyspace. I
obviously don't want to do it for the whole keyspace at once, so I'd like
to do it in groups of n, which should be configurable.
I get the first n values
you need to set default_validation_class, or metadata on the individual columns

Hello,
(I tried my best to read all I could before posting but I really
couldn't find info to answer my questions. So, here's my post.)
I have some questions.
Background:
We have a 6-node Cassandra cluster running in one data center with the
following config:
Cassandra 0.6.6
