Sylvain Lebresne commented on CASSANDRA-5314:
---------------------------------------------
bq. We TTL hints with gcgs to prevent this
Interesting. There is 2 (somewhat conflicting) things that seems weird to me
with that:
# the intent seems broken if gc_grace==0, since a TTL of 0 means no TTL at all.
# in the (not uncommon) case of using TTL on all columns without doing manual
deletion, it makes sense to use a very low gc_grace. In this case, this seems
to make hints useless, which I'm not sure is what people expect (I'll admit I
was unaware of that).
