We would like to leverage Cassandra's expiration to manage our data's lifecycle. We need to: Delete data after a period, like: 1 hour , when user clicked the "Delete" button. 

We need to read and insert the column in order to update the TTL, but this is unacceptable in our system that might need to readout gigabytes of data.

Is there a way to do this?

Best Regards!
