[jira] [Created] (SPARK-31985) Remove the incomplete code path on
aggregation for continuous mode
Jungtaek Lim created SPARK-31985:
------------------------------------
Summary: Remove the incomplete code path on aggregation for continuous mode
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.
