[jira] [Created] (NUTCH-2750) improve CrawlDbReader & LinkDbReader reader handling

Jurian Broertjes created NUTCH-2750:
---------------------------------------

             Summary: improve CrawlDbReader & LinkDbReader reader handling
                 Key: NUTCH-2750
                 URL: https://issues.apache.org/jira/browse/NUTCH-2750
             Project: Nutch
          Issue Type: Improvement
          Components: crawldb, linkdb
    Affects Versions: 1.16
            Reporter: Jurian Broertjes


The current implementation in the CrawlDbReader re-opens readers for every URL. This is not very efficient. I've implemented a modification time check that only re-opens readers on updated crawlDB.
