I re-scan the **scheduler_job.py, models/trigger.py ** again. ``` _do_scheduling ``` function has RowLock, ``` _process_executor_events ``` function also has RowLock and two functions use the same session. https://github.com/apache/airflow/blob/17d3e78e1b4011267e81846b5d496769934a5bcc/airflow/models/trigger.py#L109 has no RowLock, it will select some records which already selected by scheduler.But it will update these records, will wait the RowLock, wait until one scheduler loop is done. The process above is make sense. But it do has inconsistent problem.I have no idea where the key is. Confusing. -- This is an automated message from the Apache Git Service.
