timestamp/ttl of a cell

Hi

Can TTL of rows be  set/updated instead of complete column family?
or
Can timestamp version of a cell be decreased ? Aim is to delete some rows
whose timestamp
is set to old values so that it matches TTL of column family if tTL of
row/cell cannot be specified.

Very good question. From the shell, I'm not sure this is doable. From the
java API, you will have to use Mutation.setTTL
