  4. def apply(dataFrame: DataFrame, zoomLevel: Int, spatialColName: String, boundary: Envelope): DataFrame

    Partition the data frame to many pieces.

    Partition the data frame to many pieces. Each partition has two partition ids. Primary id is the uniform map tile id and secondary id is the non-uniformed partition id. The generated DataFrame guarantees that rows with the same secondary ids are in the partition. But each partition may contain rows with different secondary ids.
