Takes a Long Time to Load a Datanamic DataDiff Project With Only a Few Tables In It.
Datanamic DataDiff does not only store the tables in your project. All tables of the source and destination database are loaded when connecting to the database. These tables are for example used to ensure referential integrity when synchronizing the data in the tables.
A solution might be to change your database connection (Project | Project settings) so that only tables from a single schema are loaded. You can do that by specifying a schema name for the source and destination connection parameters in the Project settings dialog.
