> The same issue exists too with `Repartition` (hashing / round robin will maintain order) I'm afraid `Repartition` can not maintain the ordering. For example we have two ordered input streams [ 0, 10, 20, 25] , [ 5, 6, 7, 8] after repartition (hashing), let's say the partition count is still 2 the two output streams might become [ 0, 10, 20, 6, 8] ,[ 25, 5, 7] -- This is an automated message from the Apache Git Service.
