[OPEN-ILS-GENERAL] 3.3 hold targeter usage

[Josh Stompro]

Hello, I'm trying to understand the new options that come with the new hold
targeter, and I'm wondering how others are using it.  Is anyone using the
--soft-retarget-interval right now?

I'm considering using something along the lines of
hold_targeter.pl --soft-retarget-interval="4 hours" --retarget-interval="8
days"
running every hour.

But I'm worried that this will cause all holds to be checked every hour
after it has been 4 hours since the last retarget.  Maybe a soft-retarget
once a day is enough?

What I'm trying to achieve is to avoid the targeting churn where if a hold
isn't filled immediately, it bounces back and forth between the two most
appropriate items every retarget interval.

We have a bunch of locations that are only open a couple days a week, so
every once in a while an item never shows up on their pull list because it
is always bouncing between two target copies at locations that are only
open on the day that the item doesn't get targeted.

But I also want to make sure that if the current item is no longer
available, the hold gets re-targeted in a reasonable amount of time.  But
maybe this isn't actually needed.  Since staff marking an item missing,
damaged, withdrawn, etc automatically resets holds targeted to that item,
and retargets the hold.  So what situations are left that would cause an
item to no longer be available for a hold?

Canceling a hold transit also seems to reset the hold, so that should be
covered.

How about staff editing item properties, and changing the status that way?

How about checking out an item to another patron instead of capturing the
item for a hold?  If a customer grabs an item off the shelf that is also on
the pull list?  Or if a branch lets customers take items out of the transit
tub up until it leaves the library?  Is there anything that resets unfilled
holds that target the same item during a checkout?
