[jira] [Created] (NUTCH-2627) Fetcher to optionally filter URLs

Sebastian Nagel created NUTCH-2627:
--------------------------------------

             Summary: Fetcher to optionally filter URLs
                 Key: NUTCH-2627
                 URL: https://issues.apache.org/jira/browse/NUTCH-2627
             Project: Nutch
          Issue Type: Improvement
          Components: fetcher
    Affects Versions: 1.16
            Reporter: Sebastian Nagel
             Fix For: 1.16


When running a large web crawl it happens that a webadmin requests to immediately stop crawling a certain domain. The default Nutch workflow applies URL filters only to seeds and outlinks. Applying filters during fetch list generation is expensive with a large CrawlDb (fetch lists are usually much shorter).
