Siddharth Anand updated AIRFLOW-198:
------------------------------------
Summary: Create an OnlyRunCurrent Operator (was: Only Run Latest)
> Create an OnlyRunCurrent Operator
> ---------------------------------
>
> Key: AIRFLOW-198
> URL: https://issues.apache.org/jira/browse/AIRFLOW-198
> Project: Apache Airflow
> Issue Type: New Feature
> Reporter: Peter Attardo
> Assignee: Siddharth Anand
>
> Taken from: https://cwiki.apache.org/confluence/display/AIRFLOW/Roadmap
> "For cases where we need to only run the latest in a series of task instance
> runs and mark the others as skipped. For example, we may have job to execute
> a DB snapshot every day. If the DAG is paused for 5 days and then unpaused,
> we don’t want to run all 5, just the latest. With this feature, we will
> provide “cron” functionality for task scheduling that is not related to ETL"
> I've decided to implement this as a subclass of ShortCircuitOperator -
> OnlyRunCurrentOperator will skip downstream if the dag run being executed is
> not current.
