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? -- This message was sent by Atlassian JIRA (v6.3.4#6332)
