Alexander Uretsky commented on NUTCH-1674: ------------------------------------------ [~alparslan.avci] - Hi! Thanks a lot for this patch, it looks very promising. Can I apply it to nutch 2.2.1 (manually if needed) or do you specifically require some code from 2.3 (i.e. some other patches on top of 2.2.1)? From what I can see in the patch there seems to be no problem at all applying it to 2.2.1? but I'd like to hear it from you. Thanks! > Use batchId filter to enable scan (GORA-119) for Fetch,Parse,Update,Index > ------------------------------------------------------------------------- > > Key: NUTCH-1674 > URL: https://issues.apache.org/jira/browse/NUTCH-1674 > Project: Nutch > Issue Type: Improvement > Affects Versions: 2.3 > Reporter: Tien Nguyen Manh > Fix For: 2.3 > > Attachments: NUTCH-1674.patch, NUTCH-1674_2.patch, NUTCH-1674_3.patch > > > Nutch always scan the whole crawldb in each phrase (generate, fetch, parse, > update, index).
