[jira] [Commented] (NUTCH-882) Design a Host table in GORA

["Mathijs Homminga (Commented) (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/NUTCH-882?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13225486#comment-13225486 ] 

Mathijs Homminga commented on NUTCH-882:
----------------------------------------

Status:
I have updated the patches to match the current HEAD (nutchgora). Also added a HostDbUpdateJob which populates the host db from an existing web table (needed to fix an issue in GORA for this: https://issues.apache.org/jira/browse/GORA-105). 

I'm currently finishing some work on the NutchContext and will post the patch somewhere next week.

> Having a separate GORA table for storing information about hosts (and domains?) would be very useful for : 
> * customising the behaviour of the fetching on a host basis e.g. number of threads, min time between threads etc...
> * storing stats
> * keeping metadata and possibly propagate them to the webpages 
> * keeping a copy of the robots.txt and possibly use that later to filter the webtable
> * store sitemaps files and update the webtable accordingly
> I'll try to come up with a GORA schema for such a host table but any comments are of course already welcome
