Synchronize/replication especially update&delete how ??

i have to do sync/replication to my local database from external db (postgres) because my data is so big the mendix takes so much time to load the app its a problem because the main reason to rewite the app to mendix is for more smooth and fast dashboard,,, i try to create a sunc microflow with db connector but i only can do create new data i cant find a way to do delete and update because external db data cant be compared, i need to sync the external db to local db to be exact same table, itry to use database replication but appearantly it can only create new data ?? and i have trouble to map the table sinche when i try to pick the object its empty already did create entities in my domain model,,,   is there any easier way to replicate my database ??

You could load the data in aseparate domain model, then use microflow logic to compare the data in this model to the target domain model and decide if a create or update is needed and create the logic to delete everything that was not created or updated after that process has finished.
