BroadcastedSpatialPartitioner

class BroadcastedSpatialPartitioner extends SpatialPartitioner

The SpatialPartitioner may contain a large number of grids, which may make the serialized tasks to be larger than 1MB and trigger a warning: "WARN DAGScheduler: Broadcasting large task binary with size XXXX KB". This class is a wrapper around a SpatialPartitioner that is broadcasted to reduce the size of serialized tasks.

    Given a geometry, returns a list of partitions it overlaps.

    Given a geometry, returns a list of partitions it overlaps.

    For points, returns exactly one partition as long as grid type is non-overlapping. For other geometry types or for overlapping grid types, may return multiple partitions.
