How can that be?

For 90 days it have to be 90*24*60*60=7776000. What If you set by accident 777600 (10 times less) that will be 9 days, almost what you see.

I have the problem that one of our application is writing data into Cassandra (but not deleting them, because we should have a 90 days TTL). The application operates in 1 KS with 5 CF. my current setup: 3 node cluster and KS has a RF of 3 (I know it´s not the best setup) I can see now the problem that after 10 days most (nearly all) data are not showing anymore in the cli and also our application cannot see the data. I assume that it has something to do with the gc_grace_seconds, it is set to 10 days. I have read many documentations about tombstones, but our application doesn´t perform deletes. How can I see in the cli, if I row key has any tombstone or not. Could it be that there are some ghost tombstones?
