why has the method agg of KeyValueGroupedDataset has 4 TypedColumn parameters limit?because performace?too much timing?in my case, it needs more than 4 agg metrics at the same time, so I only agg 4 metrics and join them by key, so the join waste time. so I wish the agg method had more than 4 TypedColumn parameters -- This message was sent by Atlassian JIRA (v7.6.14#76016) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
