> Nutch always scan the whole crawldb in each phrase (generate, fetch, parse,
> update, index). When crawldb is big, the time to scan is bigger than the
> actual processing time.
> We really need to skip records while scanning using GORA-119 for example we
> can only get records belong to a specified batchId.
> In my crawl the filter reduce the time to scan from 90 min to 30 min.
