Sebastian Nagel updated NUTCH-1465:
-----------------------------------
Attachment: NUTCH-1465-sitemapinjector-trunk-v1.patch
Hi Tejas,
attached you'll find a patch for a sitemap injector. Originally written by
Hannes Schwarz, it's used by use for a couple of time. The patch contains a
revised and improved version which, however, needs some more work (see TODOs in
code).
The use case is somewhat different from way B: The sitemap injector takes URLs
of sitemaps (not via robots.txt) and injects them directly to CrawlDb (no extra
sitemapDB - do we really need an extra DB?). Robots.txt is not used as an
intermediate step/hop because experience has shown that often customers prepare
a special sitemap for the site search crawler which differs from the sitemap
propagated in robots.txt.
Btw., NUTCH-1622 would enable solution A: outlinks now can hold extra info.
