PartitionPruningRDD

java.lang.Object
- org.apache.spark.rdd.RDD<T>
- - org.apache.spark.rdd.PartitionPruningRDD<T>

All Implemented Interfaces:

java.io.Serializable
```
public class PartitionPruningRDD<T>
extends RDD<T>
```
:: DeveloperApi :: A RDD used to prune RDD partitions/partitions so we can avoid launching tasks on all partitions. An example use case: If we know the RDD is partitioned by range, and the execution DAG has a filter on the key, we can avoid launching tasks on partitions that don't have the range covering the key.

Description copied from class: RDD

:: DeveloperApi :: Implemented by subclasses to compute a given partition.

Specified by:

compute in class RDD<T>

Parameters:
split - (undocumented)
context - (undocumented)

Returns:
(undocumented)

getPartitions
```
protected Partition[] getPartitions()
```
Description copied from class: RDD

Implemented by subclasses to return the set of partitions in this RDD. This method will only be called once, so it is safe to implement a time-consuming computation in it.
The partitions in this array must satisfy the following property: rdd.partitions.zipWithIndex.forall { case (partition, index) => partition.index == index }

Specified by:

getPartitions in class RDD<T>

Returns:
(undocumented)
