> People has been having a lot of confusions about update event on idleness;
> it’s not only the matter of understanding but also comes up with various
> types of complaints. For example, since we give the latest batch ID for
> update event on idleness, if the listener implementation blindly performs
> upsert based on batch ID, they are in risk to lose metrics.
> This also complicates the logic because we have to memorize the execution for
> the previous batch, which is arguably not necessary.
> Because of this, we’d be better to move the idle event out of progress update
> event and have separate callback method for this.
