Re: Is there an api in Dataset/Dataframe that does repartitionAndSortWithinPartitions?

Dataset/DataFrame has repartition (which can be used to partition by key) and sortWithinPartitions. see for example usage here: https://github.com/tresata/spark-sorted/blob/master/src/main/scala/com/tresata/spark/sorted/sql/GroupSortedDataset.scala#L18 On Fri, Jun 23, 2017 at 5:43 PM, Keith

Hi Nguyen, This looks promising and seems like I could achieve it using cluster by. Thanks for the pointer. Regards, Keith. http://keith-chapman.com On Sat, Jun 24, 2017 at 5:27 AM, nguyen duc Tuan wrote: > Hi Chapman, > You can use "cluster by" to do what you want. >

Thanks for the pointer Saliya, I'm looking got an equivalent api in dataset/dataframe for repartitionAndSortWithinPartitions, I've already converted most of the RDD's to Dataframes. Regards, Keith. http://keith-chapman.com On Sat, Jun 24, 2017 at 3:48 AM, Saliya Ekanayake

Hi Chapman, You can use "cluster by" to do what you want. https://deepsense.io/optimize-spark-with-distribute-by-and-cluster-by/ 2017-06-24 17:48 GMT+07:00 Saliya Ekanayake : > I haven't worked with datasets but would this help https://stackoverflow. >
