Please forgive me for pulling this bit from the patches list.  I think
the relevant discussion should be on this list.

Truncating the zebraqueue table, as noted by Ryan with this patch, is
probably something Koha itself should do periodically.  Last time I
looked at the cron example I didn't see anything to this end.  The data
in the table is quite small, but there are still a lot of rows there.

This could also be applied to the action_logs table, which holds more
data, and has more rows in my installation.

Problem is troubleshooting or data retention requirements.  I suppose
there should be some config option to set a threshold on how old of data
should be kept here.  Or maybe a system preference could do that job.

I for one would like to see Koha clearing these table itself, so there
is one less thing for me to take care of.  This is especially important
to me as I didn't realize before today that these tables would be as
large as they are ( as far as number of rows is concerned ).  I would
say it's safe to assume other system admins also aren't thinking about
the size of these tables.

Comments please.
