Now, what really is the link between your corrected understanding and the
conclusion in the 2nd para? :-)

I miss the link you are using to come from para 1 to para 2.

Just because you use time UUID as the row key, there is no storage guarantee
because of that. Distribution of rows and ordering across nodes is only
based on what partitioner you are using - it is not (only) related to the
the type of the key.

May be I should just shut up now as I don't seem to be understanding you
requirement :-)
