It's not automated. You cannot specify a row to have a "default lifespan" after which it self-deletes.

If you want to remove data, you write code to:
- DELETE rows
- TRUNCATE tables or partitions
- DROP tables or partitions

Once you have written the code, you can schedule it to run automatically with DBMS_SCHEDULER()

although you cannot create a row that will automagically delete itself after some period of time, you can create a view on top of your data that will stop showing the row after a specified period of time. Simply store the expiration date and code a where clause in the view to not show the row when sysdate <= expiration date.

Maybe this will suite your needs?
