[jira] [Created] (SPARK-12425) DStream union optimisation

Guillaume Poulin created SPARK-12425:
----------------------------------------

             Summary: DStream union optimisation
                 Key: SPARK-12425
                 URL: https://issues.apache.org/jira/browse/SPARK-12425
             Project: Spark
          Issue Type: Improvement
          Components: Streaming
            Reporter: Guillaume Poulin
            Priority: Minor


Currently, `DStream.union` always use `UnionRDD` on the underlying `RDD`. However using `PartitionerAwareUnionRDD` when possible would yield to better performance.
