Karl Wettin updated LUCENE-550: ------------------------------- Attachment: trunk.diff.bz2 Introduced a method in instantiated index that appends the entire content to any other index. {code} /** * Adds the complete content of this instantiated index on to any other index using an index writer. * <p/> * This can for instance be used for * merging multiple instantiated indices * and periodically storing persistent snapshots in an FSDirectory. * <p/> * Non stored offsets are partially rebuilt. This can be improved quite a bit. See comments in code. * <p/> * The analyzer creates one complete token stream of all fields with the same name the first time it is requested, * and after that an empty for each remaining. todo: this is a problem? * <p/> * It can be buggy if the same token appears as synonym to it self (position increment 0). not really something to worry about.. or? * * @param indexWriter represents the index on wich to add all the content of this instantiated index. * @throws IOException when accessing parameter indexWriter */ public void writeToIndex(IndexWriterInterface indexWriter) throws IOException { {code} > InstantiatedIndex - faster but memory consuming index > ----------------------------------------------------- > > Key: LUCENE-550 > URL: https://issues.apache.org/jira/browse/LUCENE-550 > Project: Lucene - Java > Issue Type: New Feature > Components: Store > Affects Versions: 2.0.0 > Reporter: Karl Wettin > Assigned To: Karl Wettin > Attachments: lucene-550.jpg, test-reports.zip, trunk.diff.bz2, > trunk.diff.bz2, trunk.diff.bz2, trunk.diff.bz2 > > > An non file centrinc all in memory index. Consumes some 2x the memory of a > RAMDirectory (in a term satured index) but is between 3x-60x faster depending > on application and how one counts. Average query is about 8x faster. > IndexWriter and IndexModifier have been realized in InterfaceIndexWriter and > InterfaceIndexModifier. > InstantiatedIndex is wrapped in a new top layer index facade (class Index) > that comes with factory methods for writers, readers and searchers for unison > index handeling. There are decorators with notification handling that can be > used for automatically syncronizing searchers on updates, et.c. > Index also comes with FS/RAMDirectory implementation. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
