[Koha] Zebra (Koha 3.20.05) - Run it as a cron job or use default daemon?

[Craig Butosi]

Hi Tomas,

Really? This is great! The whole reason behind my question was to see if I could set-up my instance closer to an instant indexing set-up than in previous versions (which I believe was in 5 minute or so intervals - not terribly efficient when cataloguing). 5 seconds or fewer is outstanding. I will most certainly try out your instructions to enable. This ILS keeps getting better; learning a lot from all of you. Thank you.

Best to all,

C

Craig, since 3.18 we have an awesome indexing daemon integrated to the packages, that should be used by everyone, instead of the cronjob. Might be worth enabling by default in 3.22.

Using the indexer daemon is WAY BETTER. It seeks for updates every 5 seconds (can be lower/higher, it is user-configurable), so you get almost instant indexing (instant for the end user). Also, a lot less records get queued, so indexing time is shorter and there aren't many indexing processes running at the same time.

To enable it you need to
- Comment the rebuild_zebra.pl line in /etc/cron.d/koha-common
- Enable the indexer daemon in /etc/default/koha-common
- Restart Koha's daemons:
  $ sudo service koha-common stop ; sudo service koha-common start

And yes, do it!
