Ask HN: How are you handling data retention across your stack?

For people building SaaS with data across multiple systems (S3, DBs, caches, etc), do you actually have a clean way to manage retention/deletion across all of them? (Especially when each customer has custom policies)

Or is it more a mix of lifecycle rules, cron jobs, and manual cleanup?

How are you doing this today? I feel like this is a blocker in enterprise deals when selling to regulated industries.
