Methods in oracle.spatial.hadoop.vector.partition that return PartitioningResult

Modifier and Type	Method and Description

Methods in oracle.spatial.hadoop.vector.partition with parameters of type PartitioningResult

Modifier and Type	Method and Description
static int	PartitioningUtils.calculateNumReduceTasks(PartitioningResult partitioning) Calculates how many reduce tasks are needed to process the partitions defined in a partitioning result file
static java.util.Map<java.lang.String,java.lang.Integer>	PartitioningUtils.createPartitionsToReducersMap(PartitioningResult partitioning, int numReducers) Maps partitions to reduce tasks so the reduce tasks contain approximately the same number of elements to process
static RTree	PartitioningUtils.indexPartitions(PartitioningResult pr, SpatialOperationConfig spatialOpConf, Configuration conf) Takes a partitioning result and returns all contained partitions indexed in an r-tree
