Subj:   Re: Strange Product Join?
 
From:   Duane, Brian

The small table is duplicated and resides in spool on each amp. A merge join strategy cannot be employed because the spool cannot be sorted to same PI as the large table.

So, a product join strategy is employed with a "where a_key = b_key" constraint to do the result filtering.
