This mode is used when there are few deletes (e.g. a person table), and there is a flag in the data that is a timestamp or an increasing sequence integer. Records can be selected since the last update. Note, once you configure the column to check, you should need to run a full sync and verify that the last check incremental column is correct, so it doesnt try to select all data in the next incremental runjob to initialize the grouper_sync table incremental_index or incremental_timestamp field, since the incremental sync will abort if the relevant field is empty.
