    Description

      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?
