> Provide an option to limit MemorySink memory usage
> --------------------------------------------------
>
> Key: SPARK-24525
> URL: https://issues.apache.org/jira/browse/SPARK-24525
> Project: Spark
> Issue Type: Improvement
> Components: Structured Streaming
> Affects Versions: 2.3.1
> Reporter: Mukul Murthy
> Priority: Major
>
> MemorySink stores stream results in memory and is mostly used for testing and
> displaying streams, but for large streams, this can OOM the driver. We should
> add an option to limit the number of rows and the total size of a memory sink
> and not add any new data once either limit is hit.
