{quote}it's a bug. this isn't about tombstones resurrecting. the correct behaviour should be no results.

If the tombstone can be evicted...
bq. And lowering GC_GRACE_SECONDS on the table isn't required
Oh, it's not past GC_GRACE? That's a bug.

> In 3 node Cassandra cluster, one node has old mutation and two nodes have evict-able (crossed gc grace period) tombstone produced by TTL.
