-------------------------------
Summary: Add the switch for keeping both the old mode and the new
credit-based mode
Key: FLINK-8458
URL: https://issues.apache.org/jira/browse/FLINK-8458
Project: Flink
Issue Type: Task
Components: Network
Reporter: zhijiang
Assignee: zhijiang
After the whole feature of credit-based flow control is done, we should add a
config parameter to switch on/off the new credit-based mode. To do so, we can
roll back to the old network mode for any expected risks.
The parameter is defined as
\{{taskmanager.network.credit-based-flow-control.enabled}} and the default
value is true. This switch may be removed after next release.
