No, it's not mandatory. You can't do delta imports without delta queries though; you'd need to do a full-import. Per your query, you'd only ever do objects with rownum<=5000.

Is deltaQuery mandatory in data-config.xml ? I did it like this : <entity name="residential" query="select * from tsunami.consumer_data_01 where state='MA' and rownum <= 5000" deltaQuery="select LEMSMATCHCODE, STREETNAME from residential where last_modified > '${dataimporter.last_index_time}'"> Then my manager come and said we don't need it, this is only for incremental. I took off the line that start with deltaQuery, now in : http://localhost:8983/solr/#/db/dataimport//dataimport entity is empty, when I click the button Exwcute, nothing happened, thanks.
