Support pushing down joins in ECP #34

Closed greenlion closed 3 years ago

greenlion commented 4 years ago

Fasbit has some code to do bitmap index joins. Experiment with pushing down joins to fastbit to see how performance compares vs hash and nl joins.

Fastbit join code was a no-go. Different approach was taking for star schema optimization/pushdown joins.
