[jira] [Created] (FLINK-10790) Refactor all the StreamPartitioner
implementations into runtime module
zhijiang created FLINK-10790:
--------------------------------
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 inĀ [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.
ThisĀ 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}}.
