> Falcon Replication should support configurable delays in feed.
> By default the replication/distcp works without any delay, i.e. as soon as a
> feed is scheduled, it will start replicating with the current nominal time.
> 1. We need to support usecase of delayed replication, for example, a feed can
> be produced with a delay of n hours based on the process generating it,
> however the replication kicks of immediately and oozie goes into waiting
> state and might timeout.
> 2. We need to support parallel/concurrency for feed replication by capturing
> it from properties, user may want to run distcp parallelly to backfill data
> on another cluster.
> 3. timeout can also be set as special property.
> All these can be back-ported from Ivory release.
> 4. Need to support replication with a frequency different from the feed
> frequency, ex: a feed can have hours(1) as frequency, by default a scheduled
> feed will distcp every hour, however users should be able to set larger
> frequency like hours(6) which bulk replicates 6 hours of data in one distcp
> operation.
