Alan Woodward commented on SOLR-4478:
-------------------------------------
Have found another problem here - what to do with core-specific properties?
Core properties are passed to the SolrConfig object at construction, so there's
no way at present to use a new set of properties with an existing configset.
Same with IndexSchema, which re-uses the resource loader from SolrConfig.

> Part of moving forward to "the new way", after SOLR-4196 etc... I propose an
> additional parameter specified on the <core> node in solr.xml or as a
> parameter in the "discovery" mode core.properties file, call it configSet,
> where the value provided is a path to a directory, either absolute or
> relative. Really, this is as though you copied the conf directory somewhere
> to be used by more than one core.
> Straw-man: There will be a directory <solr_home>/configsets which will be the
> default. If the configSet parameter is, say, "myconf", then I'd expect a
> directory named "myconf" to exist in <solr_home>/configsets, which would look
> something like
> <solr_home>/configsets/myconf/schema.xml
> solrconfig.xml
> stopwords.txt
> velocity
> velocity/query.vm
> etc.
> If multiple cores used the same configSet, schema, solrconfig etc. would all
> be shared (i.e. shareSchema="true" would be assumed). I don't see a good
> use-case for _not_ sharing schemas, so I don't propose to allow this to be
> turned off. Hmmm, what if shareSchema is explicitly set to false in the
> solr.xml or properties file? I'd guess it should be honored but maybe log a
> warning?
> Mostly I'm putting this up for comments. I know that there are already
> thoughts about how this all should work floating around, so before I start
> any work on this I thought I'd at least get an idea of whether this is the
> way people are thinking about going.
> Configset can be either a relative or absolute path, if relative it's assumed
> to be relative to <solr_home>.
> Thoughts?
