Brandon Williams commented on CASSANDRA-16764:
----------------------------------------------
Is this table using LCS? This would make sense if so, since it defaults to
writing 160MB sstables, but also does not split rows, so this may already be
the sstable we're after. Does that large partition key line up with any other
findings?
