Well, actually the merkle tree computation could probably ignore gcable tombstones without much problem, which might not be such a bad idea and would probably solve much of your problem. However, when we stream the ranges that needs to be repaired, we stream sub-part of the sstables without deserializing them, so we can't exclude the gcable tombstones in that phase (that is, it's a technical reason, but deserializing data would be inefficient). Meaning that if we won't guarantee that you won't ever stream gcable tombstones. But excluding gcable tombstones from the merkle-tree computation is a good idea. Would you mind opening a JIRA ticket? -- Sylvain
