If you have :


2 columns on a hi-traffic transactional table


- one ("some_id")  high cardinality






You use both columns in SQL - "some_id" is used in JOIN and "yes_no" as a 
predicate



Would you create normal index on BOTH , just "some_id" or a composite indice 
on "some_id" + "yes_no" ?



thanks
