    read

    read

    This function will read an RDD layer based on a query.

    K

    Type of RDD Key (ex: SpatialKey)

    V

    Type of RDD Value (ex: Tile or MultibandTile )

    M

    Type of Metadata associated with the RDD[(K,V)]

    id

    The ID of the layer to be read

    rasterQuery

    The query that will specify the filter for this read.

    numPartitions

    The desired number of partitions in the resulting RDD.

    indexFilterOnly

    If true, the reader should only filter out elements who's KeyIndex entries do not match the indexes of the query key bounds. This can include keys that are not inside the query key bounds.
