Subject [jira] [Commented] (SOLR-1395) Integrate Katta
Date Fri, 30 Dec 2011 08:13:31 GMT


JohnWu commented on SOLR-1395:


  can you merge the code of my comment - 31/Oct/11 08:2 in yours, and supply the multi-core
function for the sub-proxy?
  so if the proxy and sub-proxy contains many schemas and support muli-core query, and all
the schema are independent, we can add different query and business logic, and the hot deployment
will give the solr real features which is katta can not be achieved.
  multi-core need change the code of your patch
	public SolrKattaServer(String defaultCoreName, CoreContainer coreContainer) {
		this.coreContainer = coreContainer;
		handler = new MultiEmbeddedSearchHandler(coreContainer);
		defaultCore = coreContainer.getCore(defaultCoreName);

  that's only load one solr conf folder in, so it only load one solr core
