Subject [jira] Commented: (NUTCH-443) allow parsers to return multiple Parse object, this will speed up the rss parser
Date Fri, 09 Feb 2007 16:36:06 GMT

Gal Nitzan commented on NUTCH-443:
----------------------------------

Actually, I have tested Rome after feedparser failed with OutOfMemoy. Rome has the same problem
as feedparser, both convert the feed to jdom first :(. I had to write my own implementation
for rss parser with Stax.

Not Rome and neither feedparser could handle a 100K items feed, which isn't (probably) the
common use case however it is not that far fetched use case.

HTH

> allow Parser#parse to return a Map<String,Parse>. This way, the RSS parser can
return multiple parse objects, that will all be indexed separately. Advantage: no need to
fetch all feed-items separately.
