--------------------------------

             Summary: PartitionTransformation supports DataExchangeMode property
                 Key: FLINK-12823
                 URL: https://issues.apache.org/jira/browse/FLINK-12823
             Project: Flink
          Issue Type: Improvement
          Components: API / DataStream
            Reporter: Biao Liu
            Assignee: Biao Liu
             Fix For: 1.9.0


Currently {{ResultPartitionType}} of {{DataStream}} job is hard-coded with {{PIPELINED_BOUNDED}}. Since {{DataStream}} would support batch mode, there should be way to set the {{ResultPartitionType}}.
So I propose introducing a new property {{DataExchangeMode}} of {{PartitionTransformation}}. As a first step, this would be an internal API. Maybe it would be exposed as a public API in the future.
