[jira] [Created] (FLINK-16316) Provide new base class for
StreamOperators
Piotr Nowojski created FLINK-16316:
--------------------------------------
Summary: Provide new base class for StreamOperators
Key: FLINK-16316
URL: https://issues.apache.org/jira/browse/FLINK-16316
Project: Flink
Issue Type: Sub-task
Components: API / DataStream
Affects Versions: 1.10.0
Reporter: Piotr Nowojski
Assignee: Piotr Nowojski
Fix For: 1.11.0
Current {{AbstractStreamOperator}} has at least couple of issues:
# it's using deprecated {{SetupableStreamOperator}} interface, instead of relaying on {{StreamOperatorFactory}}.
# it depends on {{OneInputStreamOperator}} and {{TwoInputStreamOperator}} interfaces, by providing indirectly implementation of methods like {{processLatencyMarker}}, {{processLatencyMarker1}} and {{processLatencyMarker2}}
Both of those things makes {{AbstractStreamOperator}} an unsuitable base implementation for {{MultipleInputStreamOperator}}. We should provide a new base class (or hierarchy of base classes), without those two limitations.
