--------------------------------------

             Summary: Return immediately if one of the sides is empty in 
NestedLoopJudgement
                 Key: SEDONA-63
                 URL: https://issues.apache.org/jira/browse/SEDONA-63
             Project: Apache Sedona
          Issue Type: Improvement
            Reporter: Martin Andersson


This is already implemented i the indexed join judgements.

If one of the sides is empty the join task won't produce any result. In that 
case we can skip initPartition() and materializing the left side.

This shaves of 10% of the execution time for one of our jobs with skewed 
partitions.
