[Koha] Cron Job Questions Koha 3 with Zebra on Ubuntu 7.10

[Ryan Higgins]

Do note that the current zebraqueue_daemon script is only suitable for
(relatively)
low-circulation libraries.  This daemon process updates the zebra index
as soon as a record is modified in your database, but is limited to updating
a single record at a time.  Since the record is modified with every circ
transaction
(so that it holds current status information), running this daemon process
is not
possible if you are (or may be) performing more than 30 transactions/minute
(on run-of-the-mill hardware).

So, unless you are a single (or few)-site, low-transaction library ( << 30
transactions/minute ),
the rebuild_zebra -z  cron script should be run rather than the
zebraqueue_daemon.  Obviously,
there's room to experiment here; beefing up the hardware could change things
significantly, and
I'm throwing numbers off the top of my head, not reading from a spec sheet.

( and to be clear, a transaction is 1 checkout or return / 1 patron , not n
checkouts or returns / patron ).
