  13. def initPartition(): Unit

    Looks up the extent of the current partition.

    Looks up the extent of the current partition. If found, match method will activate the logic to avoid emitting duplicate join results from multiple partitions.

    Must be called before processing a partition. Must be called from the same instance that will be used to process the partition.

    Iterator model for the nest loop join.

    Iterator model for the nest loop join. It returns 1 pair in the current batch. Each batch contains a list of pairs of geometries that satisfy the join condition. The current batch is the result of the current stream shape against all the build shapes.
