for ExecNode
Key: FLINK-19623
URL: https://issues.apache.org/jira/browse/FLINK-19623
Project: Flink
Issue Type: Sub-task
Components: Table SQL / Planner
Reporter: Caizhi Weng
Fix For: 1.12.0
Deadlock breakup algorithm and Multi-input operator creation algorithm need
information about the input edges of an exec node, for example what's the
priority of this input, and how the input records will trigger the output
records.
We're going to introduce a new class {{ExecEdge}} to describe this.
