Recently I upgraded from 2.2.3 to 3.7.0 (ddc distribution). Following the upgrade (though this condition may have existed prior to upgrade).. I have a table with a simple partition key and multiple clustering keys, and I have duplicates of many of the primary keys! I've tried various repair options and lots of searching, but nothing's really helping. I'm unsure of how to troubleshoot further or potentially consolidate these keys. This seems like a bug, but hopefully it's something simple I missed. I'm also willing to troubleshoot further as needed, but I could use a few getting started pointers. Example output: primary key is (partition_id,alarm_id,tenant_id,account_id,source,metric) cqlsh:alarms> select * from alarms.last_seen_state where partition_id=10 and alarm_id='59893'; partition_id | alarm_id | tenant_id | account_id | source | metric | last_seen | value--------------+----------+--------------------------------------+------------+--------+--------+---------------------------------+------- 10 | 59893 | f50f8413-57bb-4eb5-a37c-7482a63ea9a5 | 10303 | PORTAL | CPU | 2016-08-01 15:27:37.000000+0000 | 1 10 | 59893 | f50f8413-57bb-4eb5-a37c-7482a63ea9a5 | 10303 | PORTAL | CPU | 2016-08-01 15:07:15.000000+0000 | 1 Thanks, Jesse
