Subject [jira] Commented: (NUTCH-444) Possibly use a different library to parse RSS feed for improved performance and compatibility

Doğacan Güney commented on NUTCH-444:
-------------------------------------

+1 for committing feed plugin.

I would like to see parse-rss removed too. However, 

* if we are to remove it, we must make sure that it is announced properly. Otherwise, nutch-user
will just receive a ton of emails asking why nutch doesn't parse feeds even though parse-rss
is included in config :)

* it may be a good idea to optionally provide parse-rss's behavior in feed. So, one can get
either the "one parse per item" behavior or "all entries condensed into one parse" behavior.
We can do this later on, if/when it turns out that some people need the old behavior.

> As discussed by Nutch Newbie, Gal, and Chris on NUTCH-443, the current library (feedparser)
has the following issues:
> - OutOfMemory when parsing > 100k feeds, since it has to convert the feed to jdom
first
> - no support for Atom 1.0
> - there has been no development in the last year
> Alternatives are:
> - Rome 
> - Informa
> - custom implementation based on Stax
> - ??
