Re: possible to have TTL on individual collection values?
Create a table with a set as one of the columns using cqlsh, populate with a few records. Connect using the cassandra-cli, run list on your table/cf and you'll see how the sets work.

possible to have TTL on individual collection values?
If I have a settext.. can I have the individual members TTL , and not just the whole 'column' ? It's interesting considering I can use the UPDATE form whereby I just add members to the set and have a TTL on that value… which would seem to imply that I can set individual values.
