Hi Now i am considering migrate Sparkstreaming case to Flink for comparing performance.
Does flink support groupByKey([numTasks]) ,When called on a dataset of (K, V) pairs, returns a dataset of (K, Iterable<V>) pairs. If it is not exist, how to use groupBy() to implement the same function? -- View this message in context: http://apache-flink-mailing-list-archive.1008284.n3.nabble.com/Does-flink-support-groupByKey-numTasks-tp7973.html Sent from the Apache Flink Mailing List archive. mailing list archive at Nabble.com.
