Options for rebuilding indexes
Fitchett, Deborah
Kia ora,
We’ve got a situation where:
· we need to rebuild our keyword index;
· /dspace index-discovery -b takes some unknown multiple of days; and
· we have a backup outage each midnight, interrupting the reindex part-way through.
The obvious option is to turn off the backup outage until the job is complete; if we have to, we have to.
But… is there another way?
Is there a way of knowing when the job is complete (or, while it’s running, of knowing how far along it is)?
Is there a way of resuming a half-completed indexing job?
Is there a way of… like, splitting the indexing job up into sections? Somehow. IDK.
(If you can’t already tell, I don’t really *understand* the system, I just run the commands we’ve always run in the past...)

Hi Deborah.
Just a thought and a common problem that I have seen that causes index-discovery to take a long time, is that for the command line, one does not assign enough resource to the JVM. By increasing the amount of memory assigned to the JVM, you could speed up the indexing. Looking at your repository, it appears to have about 12000 items. It should not take too long to index.
BTW, Sorry about the cricket :-)

Hi Shaun,
Thanks heaps for your suggestion – we’ve finally (busy week!) had a chance to actually try it and success. J
