+\*\* The effective maximum size of the record may vary based per destination. Some destinations may
+fail to sync if a record cannot be stored, but Destinations which support
+[typing and deduping](/using-airbyte/core-concepts/typing-deduping) will adjust your record so that
+the sync does not fail, given the database/file constraints. For example, the maximum size of a
+record in MongoDB is 16MB - records larger than that will need to be modified. At the very least,
+primary keys and cursors will be maintained. Any modifications to the record will be stored within
+`airbyte_meta.changes` for your review within the destination.
