             Summary: StorageIO and configsets don't play together nicely
                 Key: SOLR-6911
                 URL: https://issues.apache.org/jira/browse/SOLR-6911
             Project: Solr
          Issue Type: Bug
            Reporter: Alan Woodward


If you use a Managed resource of some kind and a configset, then changes made by one core affect all cores that use that configset.  Similarly in cloud mode, a change made on one collection affects all collections that use the same config.

What I think would be more useful here would be if storageIO was per-collection, or per-core in non-cloud mode, and stored separately from the /config or configset.  The same thing probably applies to Noble's config-editing handlers, etc.

This also allows us to do things like make all resources read via the SolrResourceLoader immutable, and remove a whole bunch of 'if (resourceLoader instanceof ZkSolrResourceLoader)' warts all over the code.
