There are three missing pieces with our join ordering implementation:
total domain = |size of relation|
tototal domain = |size of relation| / (selectivity of relation)
.|size of relation|
does not reflect the true total domain of a join because filters reduce the size of the relation despite not affecting the selectivity of the join (assuming a primary key - foreign key join).Combining these three changes allows us to speed up TPC-H queries.
