Hi,

I´m a simple operations guy and new to Cassandra.
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?

Thx for your help
