\* Limits on workspaces, sources, and destinations do not apply to customers of

\*\* 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.
