Hello,
I'm attempting to import Wikipedia dump into XWiki using mediawiki/1.0
syntax. Since this process is quite slow and dealing with a lot of data
I'm trying to strip everything I don't need now.
While connecting visualvm to the xwiki JVM I've noticed that majority of
both CPU and memory resource is consumed by Solr index thread and Lucene
index thread. Solr leads here. To switch this off, I've switched off
completely search suggestions in Home->Administer Wiki->Search Sugest
and I've also switched Search system to be based on Database instead of
Solr. I've restarted XWiki and to my surprise from console log I see
Solr is started again and while profiling with visual vm I see again
those two index threads running and consuming majority of resources.
The platform is JDK 8, Solaris 11.1, XWiki 6.0.1 on top of PostgreSQL.
Is there any hint how to switch those index/search engines off completely?
Thanks!
Karel

This only control what is the one that is going to be displayed by
default but there is nothing in the UI to disabled SOLR.

The simplest is probably to move all the solr and lucene related jar
files out of WEB-INF/lib/ (and put them back later to index al that).
Thanks!

It’s not the first time I’ve heard people asking how to turn off SOLR. Maybe we should do
something about it to make it simpler to turn off (people will need to understand they’ll
need to reindex when they turn it on again though).
Thanks

For me particular was a little bit confusing seeing Solr running even if
I choose DB-based search. So at least a hint on this preference page
would be great to have. Having a separate page for configuring Solr
internal engine would be even nicer indeed...
Thanks!
