I tried to use Column.Ttl property but I was not successful. My simple test:

1) insert column with ttl = 3
2) get column - all is ok
3) wait for 2 seconds
4) get column - all is ok
5) wait again for 2 seconds (so column should disappear)
6) get column - I got "Thrift.TApplicationException" of type 6 with message "Internal error processing get"

Do I have to change some Cassandra configuration in order to get ttl working? Or am I doing anything in bad way?

Thank you!
