[Koha-devel] Holds Queue vs Holds to Pull

[dcook at prosentient.com.au]

Thanks for that, Phil!

 

The majority of my libraries are single-branch, so that explains my
experiences more.

 

I imagine that must only apply to bib-level holds and not specific item
holds.

For a single-branch system, they should be the same.

 

For a multi-branch system, Holds Queue first looks for an item already at
the pickup branch and puts the hold in that branch's queue (possibly even
jumping priority order if LocalHoldsPriority), or if there isn't one already
at the pickup branch depending on prefs it either looks for the cheapest
available item according to the Transport Cost Matrix if
UseTransportCostMatrix, or chooses the first branch listed in
StaticHoldsQueueWeight with an available item if StaticHoldsQueueWeight and
not RandomizeHoldsQueueWeight, or chooses a random branch from those listed
in StaticHoldsQueueWeight with an available item if StaticHoldsQueueWeight
and RandomizeHoldsQueueWeight, or chooses a random branch from all branches
with an available item if not StaticHoldsQueueWeight and
RandomizeHoldsQueueWeight, or if you mess your prefs up badly enough with
not StaticHoldsQueueWeight and not RandomizeHoldsQueueWeight, chooses the
alphabetically-first branch with an available item, thus piling all the load
on poor Aaron Aardvark Library, in each case possibly checking whether that
branch is open or closed that day if HoldsQueueSkipClosed, and puts the hold
in whatever branch's queue falls out of that.

Hi all,

 

What is the purpose of the "Holds Queue" page?

 

As far as I can tell, it duplicates "Holds to Pull" but requires a separate
cronjob and extra database tables and so on.
