Carbonite.Change (Carbonite v0.6.0) View Source

A Carbonite.Change records a mutation on a database table.

INSERT statements lead to a Change where the data field contains the inserted row as a JSON object while the changed field is an empty list.

UPDATE statements contain the updated record in data while the changed field is a list of attributes that have changed. The changed_from field may additionally contain a partial representation of the replaced record, showing only the diff to the updated record. This behaviour is optional and can be enabled with the store_changed_from trigger option.

DELETE statements have the deleted data in data while changed is again an empty list.
