--------------------------------
Summary: Refactor all the StreamPartitioner implementations into
runtime module
Key: FLINK-10790
URL: https://issues.apache.org/jira/browse/FLINK-10790
Project: Flink
Issue Type: Sub-task
Components: Network
Affects Versions: 1.8.0
Reporter: zhijiang
Assignee: zhijiang
The motivation is for refactoring {{ChannelSelector}} interface mentioned in
[FLINK-10662|https://issues.apache.org/jira/browse/FLINK-10662].
The {{ChannelSelector}} implementations are separate for stream and batch
currently, resulting in many duplicated logics for selecting channels. The root
cause is that they are locating in different modules to not reuse the existing
ones.
In general, the core runtime codes should be unified for both stream and batch
jobs as much as possible, then we can reduce the work overhead to maintain the
duplicated codes.
This jira would migrate the existing partitioner package from
{{flink-streaming-jave}} to {{flink-runtime}}. Next we want to de-duplicate
implementations for {{RoundRobinChannelSelector}} and {{OutputEmitter}}.
