Module range_join_select 

Source
Expand description

Range-native nested-loop joins wrapped by Project / Filter / Limit.

The existing join kernel only accepted a root NestedLoopJoin. Real SELECT trees are Project(Filter(Limit(Join(Scan, Scan)))). This module peels those wrappers without materialising a resident graph.
