What is "adaptive fetch schedule" as dictated by the property * db.fetch.schedule.adaptive.sync_delta* ? If this is set to true how does property *db.fetch.interval.default* come to effect ?
I guess the 'generate' phase checks for the modified timestamp of every page in the crawldb. If a page does change, Nutch decides whether to re-fetch based on the property - "* db.fetch.schedule.adaptive.sync_delta_rate*". Is this assumption correct ? If yes, what does the default fetch interval mean in this context. The re-fetch seems to be affected for such cases by how often I run "generate".
