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

[Tomas Cohen Arazi]

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!
