Abstract
Techniques are described herein for processing queries comprising joins specifying a plurality of tables. The techniques involve partitioning the tables by assigning rows to partitions. One or more partition maps may be generated to indicate the partitions. Subsequent tables may be partitioned based on the generated partition maps. The partitions may be used to determine results for the joins.
