> In the above example, the validity time is "the time interval when the feed is valid on this cluster". After the validity time ends, falcon is not expected to perform any operations on the feed. The retention job for this feed will be run from validity start time up to validity end time, and will delete any feed instances older than 10 hours. Some instances of Feed will never be deleted. In the above example, feed instances at between 2015-10-30T00:00Z and 2015-10-30T10:00Z will never be deleted.
> Ideally, the retention coordinator job should run from "validity start time" up to "validity end time + retention age limit" to ensure all instances are handled.
