From a storage perspective, is there a significant difference between deleting a record vs. deleting data from fields on the record but keeping the data itself?
Our org has a lot of Cases and custom objects that have relations to Contacts. In some cases, however, when a Contact is no longer a client, we have some sensitive information we'd like to remove from our org. However, simply deleting the record would potentially orphan those related records, so we'd much rather keep the Contact around and delete the sensitive information. I have been asked if keeping these inactive Contacts around could lead to storage issues on down the line, even if we wipe all the fields except for a few on the Contact, and I genuinely don't know the answer.
