Subject [jira] Commented: (SOLR-1632) Distributed IDF
Date Fri, 11 Dec 2009 16:41:18 GMT


Otis Gospodnetic commented on SOLR-1632:

I didn't look a the patch, but from your comments it looks like you already have that "1 merged
big idf map", which is really what I was aiming at, so that's good!

I was just thinking that this map (file) would be periodically updated and pushed to slaves,
so that slaves can compute the global IDF *locally* instead of any kind of extra requests.
