Hi all,
solr supports system property substitution as you can see at http://wiki.apache.org/solr/SolrConfigXml#System_property_substitution
So the two mentioned parameters can be tuned as you like using autoCommit and autoSoftCommit features.
The strange behaviour noticed by Robin is because the discovery consumer call an index method that do not call the programmatically solr commit, which the update-discovery do well (as noticed by helix).
Imho the https://github.com/DSpace/DSpace/blob/master/dspace-api/src/main/java/org/dspace/discovery/IndexEventConsumer.java#L170 could be modified with calling the "void indexContent(Context context, DSpaceObject dso, boolean force, boolean commit)" method and force commit to true (or get this information from configuration to left the user to use autoSoftCommit in case the commit property is false)
Hope this helps.

Regards,

Luigi Andrea

Hi,

I suspect, but I am definitely not sure, that no automatic commits will be
done with the config as it is. If I run an 'optimize' using the Solr Admin
client, or restart Tomcat, then the indices get updated. Not a big issue,
I think we maybe just need to set some default values. I'll do a wee bit
more investigation.

Cheers.

I can confirm I'm seeing the same thing in DSpace 4 and that DSpace 3
had actual numbers there. I join you in your confusion.

Can you observe any ill effects? I didn't notice anything wrong and I
ran "update-discovery-index -f" on ~20k items yesterday.
