http://issues.apache.org/bugzilla/show_bug.cgi?id=30421 Merging indexes leads to out-of-memory condition Summary: Merging indexes leads to out-of-memory condition Product: Lucene Version: 1.4 Platform: Other OS/Version: Linux Status: NEW Severity: Major Priority: Other Component: Index AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] Version: 1.4 Final Platform: Red Hat 9 Method: IndexWriter.addIndexes My experience with merging indexes of any size results in one outcome: java.lang.OutOfMemoryError. This is true even on a 1GB machine where almost all free memory is allocated to the VM. Is there a way to reliably merge indexes? I've marked this issue as 'major' for the following reason: Without an efficient merge capability, the developer must deploy hundreds of 'little' indexes that will need to be searched in parallel. Unfortunately, this constraint plus java makes an application too slow to be usable in a production environment. Thank you for looking into this issue. >>>>>>>>> sample code Directory dest = FSDirectory.getDirectory( destination, true); IndexWriter writer = new IndexWriter( dest, new TermAnalyzer( StopWords.SEARCH_MAP), true); writer.addIndexes( sources); writer.optimize(); writer.close(); --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
