Apache Spark reassigned SPARK-8835:
-----------------------------------
Assignee: Apache Spark
> Provide pluggable Congestion Strategies to deal with Streaming load
> -------------------------------------------------------------------
>
> Key: SPARK-8835
> URL: https://issues.apache.org/jira/browse/SPARK-8835
> Project: Spark
> Issue Type: Sub-task
> Components: Streaming
> Reporter: François Garillot
> Assignee: Apache Spark
>
> Second part of [SPARK-7398|https://issues.apache.org/jira/browse/SPARK-7398]
> (which has an over-arching, high-level design doc).
> An (outdated) [PoC
> implementation|https://github.com/huitseeker/spark/tree/ReactiveStreamingBackPressureControl/]
> exists.
> Note that throttling in the current (Spark 1.5.0) way pushes down the
> (fast-overflowing) buffer of received elements down to the TCP stack, which
> then has to deal with the break. This can be witnessed here :
> https://github.com/skyluc/spark-streaming-testbed/tree/test-runs-006/test-runs-006
