Subject Re: [BETA RELEASE] Apache Cassandra 1.2.0-beta2 released

Actually, if we're going to be precise, it's -2^63 to 2^63 - 1.
Long.MIN_VALUE is not a valid token for technical reasons.

Do note that you can still not change partitioner, so the new partitioner
is for new cluster. But that does mean that for existing ones you'll have
to make sure you do keep RandomPartitioner in the yaml when you "merge" old
and new yaml. It's in the NEWS file however (that I do encourage you to
read, at least for new major versions).
