Stephan Ewen created FLINK-17854:
------------------------------------
Summary: Use InputStatus directly in user-facing async input APIs
(like source readers)
Key: FLINK-17854
URL: https://issues.apache.org/jira/browse/FLINK-17854
Project: Flink
Issue Type: Improvement
Components: API / Core
Reporter: Stephan Ewen
Assignee: Stephan Ewen
Fix For: 1.11.0
The flink-runtime uses the {{InputStatus}} enum in its
{{PushingAsyncDataInput}}.
The flink-core {{SourceReader}} has a separate enum with the same purpose.
In the {{SourceOperator}} we need to bridge between these two, which is clumsy
and a bit inefficient.
We can simply make {{InputStatus}} part of {{flink-core}} I/O packages and use
it in the {{SourceReader}}, to avoid having to bridge it and the runtime part.
