Class JoinExtractFilterRule

All Implemented Interfaces:

@Enclosing public final class JoinExtractFilterRule extends AbstractJoinExtractFilterRule
Rule to convert an inner join to a filter on top of a cartesian inner join.

One benefit of this transformation is that after it, the join condition can be combined with conditions and expressions above the join. It also makes the FennelCartesianJoinRule applicable.

Can be configured to match any sub-class of Join, not just LogicalJoin.
