Scheduled Deletions At Scale | Sneha Padgalwar

At Meta, a large part of our data is ephemeral in nature, such as Instagram or Meta Stories which need to be deleted after a specific time regardless of the action taken by the user. This is sometimes referred to as Time to Live (TTL). Deletions may be registered to start at an arbitrary point of time in the future. Developers can achieve this at object creation time by virtue of creating an object of a type under TTL. The Deletion Infrastructure team at Meta built the Schedule Deletion (SD) Infrastructure, that allows us to Schedule and Track massive volumes of deletions from days to years in future.
