Subj:   Re: How to avoid Product join

For the case cited: duplicating the small table on all AMPs, scanning the large table, and doing a product join of each large table row with the small table (via in-memory lookup) is very likely the best performing plan.

Why do you think avoiding the product join would be desirable?
