Description

When a schema is shared, it should not have access to the classes of a specific core. The core may come and go but the shared schema may continue tolive . So how do we implement that?

If a schema is shared, create a new SolrResourceLoader specifically for that schema object. The classpath should be the same as the classpath for the SRL in CoreContainer. As and when we implement loading schema plugins from packages, they too should be accessible. The SRL created for this schema should be able to load resources from ZK in the path /configs/<configset-name>. This SRL should be discarded when the schema no destroyed
