> I've seen a few items on the mailing lists recently surrounding updating a schema on the file system and not seeing the changes get propagated.  while I think that automatically detecting schema changes on disk may be unrealistic, I do think it would be useful to be able to update the schema without having to bounce the webapp.  the forthcoming patch adds a method to SolrCore to do just that as well as a request handler to be able to call said method.  
> The patch as it exists is a straw man for discussion.  The one thing that concerned me was making IndexScheam schema non-final in SolrCore.  I'm not quite sure why it needs to be final to begin with so perhaps someone can shed some light on the situation.  Also, I think it would be useful to be able to upload a schema through the admin GUI, have it persisted to disk and then call relaodSchema()but that seemed like a good bit of effort for a patch that might not even be a good idea.
> I'd also point out that this specific problem is one I've been trying to address recently and while I think it could be solved with various dynamic fields the combination of all the options for fields seemed to create too many variables to make useful dynamic name patterns.
> Thoughts?
