The optimizer can push filter predicates down into the data source, enabling the physical execution to skip irrelevant data. Spark supports push down of predicates to the data source. Is this feature also available / expected for JDBC? (From inspecting the DB logs I can see it's not the default behavior right now - the full query is passed to the DB, even if it's later limited by spark filters) MORE DETAILS Running Spark 1.5 with PostgreSQL 9.4

The JSON

The query is meant to find the ID, Start Date, and Price of Event2, Following Event1 by 1 Day. The code WORKS fine. But I don't understand HOW. Could someone explain as thoroughly as you can- what the different parts of the query are and what they do? SELECT event2 . id , event2 . startdate , event2 . price FROM mm_eventlist_dates event1 JOIN mm_eventlist_dates event2 ON event2 . startdate = date_add ( event1 . enddate , INTERVAL 1 DAY ) WHERE event1 . id = $id

I've set the autoscroll set to true on the panel. But when the content of the picturebox is larger then the height of the panel/picturebox no scrollbars are shown.
