Apache Spark reassigned SPARK-11632:
------------------------------------
Assignee: Apache Spark
> Filter out empty partition for KafkaRDD
> ---------------------------------------
>
> Key: SPARK-11632
> URL: https://issues.apache.org/jira/browse/SPARK-11632
> Project: Spark
> Issue Type: Improvement
> Components: Streaming
> Reporter: Saisai Shao
> Assignee: Apache Spark
> Priority: Minor
>
> For KafkaRDD, each partition's processed message number is calculated
> beforehand, so empty partition could be filtered out to avoid submitting
> unnecessary tasks. This could alleviate scheduling overhead if there's no
> data come in, also makes dynamic allocation effective to shrink the resources
> (no pending tasks).
> For other receiver-based DStream, BlockRDD already support empty one, so if
> no data injected at that time period, there will be no task submitted.
