[jira] [Commented] (SOLR-4478) Allow cores to specify a named
config set
[ https://issues.apache.org/jira/browse/SOLR-4478?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13710994#comment-13710994 ]
Erick Erickson commented on SOLR-4478:
--------------------------------------
If anyone has some spare cycles to work on this, please let me know. It's not that I'm stymied, I'm just having a really hard time finding the cycles to work on it. I can get this patch compiling again (after Alan and Mark and I did some reorganizing of all the persistence stuff, this is probably in kind of poor shape).
Otherwise I'll get to it when I can, but I've been in that state for a couple of months now. I'm not looking to pass this off to someone completely, unless someone really wants it all for themselves, just looking for some extra energy.

> 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?
