After upgrading from 1.0.8 I see that now the directory structure has changed
and has a structure like keyspacecolumnfamily (part of the 1.1.x migration).
But I also see that directories appear like keyspacecolumnfamily-old, and
the content of that 'old' directory is only one file
created the -old CF dir. Does the timestamp
indicate it was created the time the server first started as a 1.2 node?
Cheers

Hi,
I was trying to implement my own ordered partitioner and got into problems.
The current DecoratedKey is using a ByteBufferUtil.compareUnsigned for
comparing the key. I was thinking of having a signed comparison, so I thought
of making my own DecoratedKey, Token and Partitioner. That way I
: Re: ordered partitioner
Not in general, no. There are places, like indexing, that need to use a local
partitioner rather than the global one.
Which uses of the DK constructor looked erroneous to you?

Ok. Quick other question then. Did you issue deletion and/or used TTLs for that
