> test_join_queries.py is expensive to run in exhaustive exploration because it run many test dimension permutation, but actually never exercise some of the dimensions. Those redundant tests are follows:
>  * Have mt_dop dimension, but not exercising it:
> test_outer_to_inner_joins
> test_single_node_nested_loop_joins
>  * Have batch_size dimension but not exercising it:
> test_outer_to_inner_joins
> test_single_node_nested_loop_joins
> test_single_node_nested_loop_joins_exhaustive
> test_semi_joins_exhaustive
>  * Have enable_outer_join_to_inner_transformation dimension but not exercising it:
> All TestJoinQueries except test_outer_to_inner_joins
> test_miss_tuple_joins is also valid to run with much fewer test dimension because it mainly test correctness of predicate pushdown during planning.
