----------------------------------
Summary: Determine the initial status before receiving the first
RecordAttributes
Key: FLINK-33890
URL: https://issues.apache.org/jira/browse/FLINK-33890
Project: Flink
Issue Type: Sub-task
Components: Runtime / Task
Reporter: Xuannan Su
Currently, all the operators are initialized with non-backlog mode. Ideally, we
should determine the initial status before receiving the first
{{RecordAttributes}} so that we don't have to initialize the operator in
non-backlog mode and immediately switch to backlog mode before processing any
records.
