I’ve two tables that I want to question, tableA has ~53_000 rows whereas tableB has ~530M rows.
SELECT b.some_field AS discipline, a.* FROM tableA a LEFT JOIN tableB b ON a.user_id = b.user_id AND a.numeric_field >= b.numeric_field AND a.numeric_field <= b.other_numeric_field LIMIT 10;
This kills the question engine as a result of the correct hand facet is way greater than the left, so I feel for each row on the left it has to question the correct.
In such case (dimension of proper hand facet being a lot greater than left) what’s the finest to do:
I’m serious about two potentialities:
- switching up sides and utilizing proper be part of
- making a doubtlessly a lot smaller desk by querying the rows that exist in the correct hand facet and be part of that desk
