Sylvain Lebresne commented on CASSANDRA-6434:
---------------------------------------------
I'm confused. That ticket description sounds like it's about lowering the
lifetime of tombstones in the system but you make it sounds like it's not about
that anymore. If this doesn't allow to lower gc_grace, then why do we need that
extra safety? Is it just really only extra safety (to be clear, I'm really not
a fan of the changes to LivenessInfo and DeletionTime and I'd like to see if we
can avoid it, but before that I need to understand why we're doing this ticket
in the first place).

> Since the reason for gcgs is to ensure that we don't purge tombstones until
> every replica has been notified, it's redundant in a world where we're
> tracking repair times per sstable (and repairing frequentily), i.e., a world
> where we default to incremental repair a la CASSANDRA-5351.
