> @wangyum Thanks for your response. If the incoming data is not even distributed by the repartitioning key, wouldn't this strategy create issues when there is skew in the data ? i.e we may end up with potentially very large partitions ? +1 for this concern , maybe we should add an adaptive procedure to adjust the number of partitions for the large partition key value. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
