table action : append or overrwite?
hi every one. When creating a pipeline with the 'Copy Data' activity from one lake file explorer into a lakehouse, I want to avoid duplication. For example, if I have 500 rows in the local file and in my lakehouse, and I add 30 new rows in local, I want the pipeline to extract only the 30 new rows to lakehouse, not all 530 rows. In other words, I want to avoid duplication. Therefore, which table action should I choose: append or overwrite?
