--------------------------------
Summary: Add a new type UNDEFINED of shuffle mode
Key: FLINK-13099
URL: https://issues.apache.org/jira/browse/FLINK-13099
Project: Flink
Issue Type: Improvement
Components: API / DataStream
Reporter: Biao Liu
Assignee: Biao Liu
Fix For: 1.9.0
The {{UNDEFINED}} type is the default value of shuffle mode. If there is no
specific {{PartitionTransformation}}, the shuffle mode would be {{UNDEFINED}}.
This new shuffle type leaves some space for optimization later. The
optimization might be based on resources or some global settings.
