Because the vacuum command permanently deletes all files containing deleted records, deleted records may be accessible with time travel for around 24 hours.

Because the default data retention threshold is 24 hours, data files containing deleted records will be retained until the vacuum job is run the following day.

Because Delta Lake time travel provides full access to the entire history of a table, deleted records can always be recreated by users with full admin privileges.

Because Delta Lake's delete statements have ACID guarantees, deleted records will be permanently purged from all storage systems as soon as a delete job completes.

Because the default data retention threshold is 7 days, data files containing deleted records will be retained until the vacuum job is run 8 days later.

All data should be deleted biweekly; Delta Lake's time travel functionality should be leveraged to maintain a history of non-PII information.

Data should be partitioned by the registration field, allowing ACLs and delete statements to be set for the PII directory.

Because the value field is stored as binary data, this information is not considered PII and no special precautions should be taken.

Separate object storage containers should be specified based on the partition field, allowing isolation at the storage level.

Data should be partitioned by the topic field, allowing ACLs and delete statements to leverage partition boundaries.
