--------------------------------------

             Summary: pyspark.DStream top method
                 Key: SPARK-8827
                 URL: https://issues.apache.org/jira/browse/SPARK-8827
             Project: Spark
          Issue Type: Improvement
          Components: PySpark, Streaming
            Reporter: Emanuele Cesena
            Priority: Minor


Is there a reason for not having DStream.top?
Any issues with the following definition?

```
    def topPartition(partition):
        return sorted(partition, key=lambda p: p[1], reverse=True)[:10]

    def top(counts):
        return counts.transform(lambda rdd: rdd.mapPartitions(topPartition)
            .sortBy(lambda p: p[1],ascending=False))
```
