julien nioche updated NUTCH-702: -------------------------------- Attachment: lazyMetadataInstanciation.patch patch for lazy instanciation of metadata in crawldatum > Lazy Instanciation of Metadata in CrawlDatum > -------------------------------------------- > > Key: NUTCH-702 > URL: https://issues.apache.org/jira/browse/NUTCH-702 > Project: Nutch > Issue Type: Improvement > Affects Versions: 1.0.0 > Reporter: julien nioche > Attachments: lazyMetadataInstanciation.patch > > > CrawlDatum systematically instanciates its metadata, which is quite wasteful > especially in the case of CrawlDBReducer when it generates a new CrawlDatum > for each incoming link before storing it in a List. > Initial testing on the lazy instanciation shows an improvement in both speed > and memory consumption. I will generate a patch for it ASAP -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
