> Add back-pressure to Spark Streaming
> ------------------------------------
>
> Key: SPARK-7398
> URL: https://issues.apache.org/jira/browse/SPARK-7398
> Project: Spark
> Issue Type: Improvement
> Components: Streaming
> Affects Versions: 1.3.1
> Reporter: François Garillot
> Priority: Critical
> Labels: streams
>
> Spark Streaming has trouble dealing with situations where
> batch processing time > batch interval
> Meaning a high throughput of input data w.r.t. Spark's ability to remove data
> from the queue.
> If this throughput is sustained for long enough, it leads to an unstable
> situation where the memory of the Receiver's Executor is overflowed.
> This aims at transmitting a back-pressure signal back to data ingestion to
> help with dealing with that high throughput, in a backwards-compatible way.
> The design doc can be found here:
