Noble Paul updated SOLR-1306: ----------------------------- Description: Persisting and loading details from one xml is fine if the no:of cores are small and the no:of cores are few/fixed . If there are 10's of thousands of cores in a single box adding a new core (with persistent=true) becomes very expensive because every core creation has to write this huge xml. Moreover , there is a good chance that the file gets corrupted and all the cores become unusable . In that case I would prefer it to be stored in a centralized DB which is backed up/replicated and all the information is available in a centralized location. We may need to refactor CoreContainer to have a pluggable implementation which can load/persist the details . The default implementation should write/read from/to solr.xml . And the class should be pluggable as follows in solr.xml {code:xml} <solr> <dataProvider class="com.foo.FooDataProvider" attr1="val1" attr2="val2"/> </solr> {code} There will be a new interface (or abstract class ) called SolrDataProvider which this class must implement was: Persisting and loading details from one xml is fine if the no:of cores are small and the no:of cores are few/fixed .
