Taus Brock-Nannestad c2f112cb92 Python: Filter _before_ the cartesian product
It's always a sad thing to see a good plan go wrong:

86860032 ~0%      {4} r26 = JOIN r19 WITH DataFlowPublic::TupleElementContent#class#ff CARTESIAN PRODUCT OUTPUT Lhs.0 'nodeFrom', Lhs.1 'nodeTo', Rhs.0, Rhs.1
129256   ~3%      {4} r27 = SELECT r26 ON In.3 <= 7
129256   ~0%      {3} r28 = SCAN r27 OUTPUT In.0 'nodeFrom', In.2 'c', In.1 'nodeTo'

Happily, now it looks like this:

129256  ~0%      {3} r20 = JOIN r19 WITH DataFlowPrivate::small_tuple#f CARTESIAN PRODUCT OUTPUT Lhs.0 'nodeFrom', Rhs.0, Lhs.1 'nodeTo'
