> Batchlog writes with the same key are never retried. This means that if a
> batchlog row is in the memtable, it can't be in any of the sstables, ever. In
> such cases we don't need to write a tombstone to disk. We can purge the row
> completely from the memtable and only write a tombstone if the row had been
> flushed already (if it's not in the memtable then it must be in one of the
> sstables).
