Solr will handle 3 million items quite well (you'll need to be careful, but there are a very large number of installations around with that kind of size index).
I don't think I'd recommend doing Lucene on Cassandra for that scale (it's a less mature solution, and there aren't a lot of people working on it yet). If you are interested in working on it, though, I did modify Jake's Lucanrda index to make it suitable for running Solr on: http://nicklothian.com/blog/2009/10/27/solr-cassandra-solandra/ Nick > -----Original Message----- > From: David MARTIN [mailto:[email protected]] > Sent: Saturday, 19 December 2009 12:01 AM > To: [email protected] > Subject: Re: Is Cassandra suitable for multi criteria search engine > > Is a 3 million records set not a big deal for Solr?
