----------------------------------------

             Summary: Resurrected empty rows on update to 3.x
                 Key: CASSANDRA-12620
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-12620
             Project: Cassandra
          Issue Type: Bug
            Reporter: Collin Sauve


We had the below table on C* 2.x (dse 4.8.4, we assume was 2.1.15.1423 according to documentation), and were entering TTLs at write-time using the DataStax C# Driver (using the POCO mapper).

Upon upgrade to 3.0.8.1293 (DSE 5.0.2), we are seeing a lot of rows that:

* should have been TTL'd
* have no non-primary-key column data
