I feel that there is a significant bit of confusion here.
You CAN use start/finish when using get_range_slices with random partitioner.
But you can't make any assumptions about what key will be next in the range
which is the whole point of "random". If you do know a specific key that you

This is a data modeling question, not operational like my previous ones today.
I have a data model where I'm going to have some 1:1 relationship between a
CF1/Key1/Col value and another CF2/Key where the value in CF1/Key1/Col is the
CF2/Key.
CF1 will grow to have 1B+ keys. CF1 will have 10...N
Thanks in advance.

Here's the scenario: would like R = N where N is the number of nodes. Let's say
8.
1. Create first node, modify storage-conf.xml and change the to be the
ip of the node. Change replication factor to 8 for CF of interest. Start the
puppy up.
2. Create 2nd node, modify storage-confg.xml and ch

I've seen numerous anecdotal references that the Sun JVM performs better.
Is there a reason why the debian packaging for Cassandra installs the OpenJDK
version?
What would it take to create an alternative apt-get package that pulls Sun JVM
rather than OpenJDK?

Could you clarify what you mean by "remove command"? Remove all columns leaving
a row key?
Did you use nodetool to force a flush and then compact after GCGraceSeconds?
