Cassandra with vnode and ByteOrderedPartition
We're using ByteOrderedPartition to programmatically choose the machine
which a objet will be inserted.*
*How can I use *ByteOrderedPartition *with vnode on Cassandra 1.2?

You don't have to use vnodes in Cassandra 1.2 - set num_tokens to 1 to
disable.

We were able to implement ByteOrderedPartition on Cassandra 1.1 and insert
an object in a specific machine.
However, with Cassandra 1.2 and VNodes we can't implement VNode with
ByteOrderedPartitioner
to insert an object in a specific machine.

Don't. Managing tokens with ByteOrderedPartitioner is very hard anyway,
but with vnodes you have to manually manage many more tokens. Also I doubt
BOP + vnodes has had any production testing.
