Abstract
A query optimizer identifies a condition that supports a remote nested join. A first Access Module Processor (AMP) is sent the condition to obtain a first set of rows that satisfy the condition from a first table and the first AMP is instructed to perform the remote nested join with a second remote AMP to acquire a second set of rows that satisfy the condition from a second table. The first AMP joins the first set of rows and the second set of rows as a join result, which is returned to the query optimizer.
