----------------------------------
Resolution: Incomplete
> Add memory back pressure for Spark Streaming
> --------------------------------------------
>
> Key: SPARK-13799
> URL: https://issues.apache.org/jira/browse/SPARK-13799
> Project: Spark
> Issue Type: Improvement
> Components: DStreams
> Affects Versions: 2.0.0
> Reporter: Liwei Lin(Inactive)
> Priority: Major
> Labels: bulk-closed
>
> The back pressure mechanism added in Spark 1.5.0 is great in keeping the whole application in a stable state. But even with back pressure enabled, we have, for some times, experienced Receiver side’s OOME when facing sudden data burst.
> This proposes to add memory back pressure at the Receiver side, as a complement to the current back pressure mechanism, to better keep the application in a stable state.
