             Summary: Add an RDD.samplePartitions method for partition-level sampling
                 Key: SPARK-2032
                 URL: https://issues.apache.org/jira/browse/SPARK-2032
             Project: Spark
          Issue Type: Improvement
          Components: Spark Core
            Reporter: Matei Zaharia


This would allow us to sample a percent of the partitions and not have to materialize all of them. It's less uniform but much faster and may be useful for quickly exploring data.
