# Full Synchronization

Full synchronization will read all available data in the data source and re-ingest every record each time the synchronization occurs.  This is the only method available for uploaded files.  For database tables, this method is only recommended when there is no table field that can be used as a primary or incremental key for another any of the other synchronization methods.
