Key: FLINK-7394
URL: https://issues.apache.org/jira/browse/FLINK-7394
Project: Flink
Issue Type: Sub-task
Components: Core
Reporter: zhijiang
Assignee: zhijiang
Fix For: 1.4.0
This is a part of work for credit-based network flow control.
The basic works are:
* The exclusive buffers per channel are assigned to {{RemoteInputChannel}}
directly during registering task.
* {{RemoteInputChannel}} implements {{BufferRecycler}} interface to manage the
exclusive buffers itself.
* {{RemoteInputChannel}} implements {{BufferPoolListener}} interface to be
notified available floating buffers from buffer pool.
* {{RemoteInputChannel}} maintains unannounced credit and current sender
backlog.
