I've posted a similar question few days ago, but our needs have gone a bit further.
I need to develop two plugins which need to be persistent throu the whole indexing and updating process The first one need to open a connection to a mysql instance (and query that connection during every document processing) The second one uses a java library (classifier4j) which is a Bayesian categorization system (and doesn't talk to a db). This one learns while matching, so the object needs to be created at the very beginning of the indexing and should be available for all the documents (i cannot create the object for every object, because i'd miss the learning feature) For the first one i could use a dataimporthandler, but i'm not sure about it: i don't need to import the whole db, but just the occurencies matching a particular condition for each document. About the second one, i'm blind. Is there a place in solr where i can create the connection object and the categorizer object before everything else, and have them available to all documents? Thanks all in advance! -- View this message in context: http://lucene.472066.n3.nabble.com/Solr-custom-plugins-is-it-possible-to-have-them-persistent-tp3292781p3292781.html Sent from the Solr - User mailing list archive at Nabble.com.
