> CASSANDRA-6117 addressed the death of Cassandra by column tombstones, and
> whose fix was to raise an error when reading more tombstones than a
> threshold. I think it is an emergency action, rather than a fix.
> We have had this issue for long. So I wondered, in the first place, if it is
> really necessary to collect non-gc-able tombstones, which could cause
> concurrent mode failures, and OOM eventually?
> Actually, I was surprised by the fact that Cassandra takes them into
> consideration. Rather, I prefer to raise a threshold, and tell Cassandra to
> ignore tombstones for digest calculation of RR because a repair is running
> regularly.
> I guess there are some people like me, but not all. So what about adding a
> new configuration option if Cassandra ignores column tombstones for RR or not?
