Erick Erickson updated SOLR-1306: --------------------------------- Attachment: SOLR-1306.patch Patch adding multi-thread core creation that insures that multiple calls to create the same core all return the same object. > Support pluggable persistence/loading of solr.xml details > --------------------------------------------------------- > > Key: SOLR-1306 > URL: https://issues.apache.org/jira/browse/SOLR-1306 > Project: Solr > Issue Type: New Feature > Components: multicore > Reporter: Noble Paul > Assignee: Erick Erickson > Fix For: 4.1 > > Attachments: SOLR-1306.patch, SOLR-1306.patch, SOLR-1306.patch > > > 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 -- This message is automatically generated by JIRA.
