> "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"
