> Key: SPARK-31985
> URL: https://issues.apache.org/jira/browse/SPARK-31985
> Project: Spark
> Issue Type: Task
> Components: Structured Streaming
> Affects Versions: 3.1.0
> Reporter: Jungtaek Lim

>
> During work I realized we left some incomplete code parts on supporting aggregation for continuous mode. (shuffle & coalesce)
>
> The work had been occurred around first half of 2018 and stopped, and no work has been done for around 2 years, so I don't expect anyone is working on this.
>
> The functionality is undocumented (as the work was only done partially) and continuous mode is experimental so I don't feel risks to get rid of the part.
