[PR] expand parameter [spark]
huanccwang opened a new pull request, #44356:
URL: https://github.com/apache/spark/pull/44356
In some business scenarios, the columns we aggregate are not fixed and unknown. We need to perform dynamic aggregation based on business configuration information, so we need to pass in dynamic columns,I looked at the source code and found that when multiple columns are passed in, it is also converted to Seq, so I expanded the parameters of groupBy() to support passing in Seq.
