Zhu Zhu created FLINK-28193: ------------------------------- Summary: Enable to identify whether a job vertex contains source/sink operators Key: FLINK-28193 URL: https://issues.apache.org/jira/browse/FLINK-28193 Project: Flink Issue Type: Sub-task Components: Runtime / Coordination Reporter: Zhu Zhu Fix For: 1.16.0
Speculative execution does not support sources/sinks in the first version. Therefore, it will not create speculation instances for vertices which contains source/sink operators. Note that a job vertex with no input/output does not mean it is a source/sink vertex. Multi-input sources can have input. And it's possible that the vertex with no output edge does not contain any sink operator. Besides that, a new sink with topology can spread the sink logic into multiple job vertices connected with job edges. -- This message was sent by Atlassian Jira (v8.20.7#820007)
