Lewis John McGibbney commented on NUTCH-1674:
---------------------------------------------

This is a difficult one to commit right now. 
For starters the formatting is not correct. 
The more immediate problem I see is that we cannot rely upon *all* Gora 
SNAPSHOT artifacts right now. gora-cassandra needs work for sure.
I see no problem with this remaining as a high priority task prior to next 2.x 
release. First we need to release a stable 0.4 Gora into the wild before we can 
implement this patch into Nutch.
Does anyone disagree with this?

> 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.
