[jira] [Commented] (NUTCH-2666) Increase default value for
http.content.limit / ftp.content.limit / file.content.limit
[ https://issues.apache.org/jira/browse/NUTCH-2666?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16785819#comment-16785819 ]
Sebastian Nagel commented on NUTCH-2666:
----------------------------------------
Any objections? It's a huge jump but the it may be sufficient as default for the next years.

> Key: NUTCH-2666
> URL: https://issues.apache.org/jira/browse/NUTCH-2666
> Project: Nutch
> Issue Type: Improvement
> Components: fetcher
> Affects Versions: 1.15
> Reporter: Marco Ebbinghaus
> Priority: Minor
> Fix For: 1.16

> The default value for http.content.limit in nutch-default.xml (The length limit for downloaded content using the http://
> protocol, in bytes. If this value is nonnegative (>=0), content longer
> than it will be truncated; otherwise, no truncation at all. Do not
> confuse this setting with the file.content.limit setting.) is set to 64kb. Maybe this default value should be increased as many pages today are greater than 64kb.
> This fact hit me when trying to crawl a single website whose pages are much greater than 64kb and because of that with every crawl cycle the count of db_unfetched urls decreased until it hit zero and the crawler became inactive (because the first 64 kB contained always the same set of navigation links)
> The description might also be updated as this is not only the case for the http protocol, but also for https.
