title: Katta vs Lucene + Infinispan
body: <p>Lucene can work with disturbed infinispan cache. I'm wondering what is the moment to move from lucene + infinispan to Katta based on hadoop? When I'll be more effective to use Katta and when Lucene+infinispan? I've read that hadoop is not suitable for real-time systems, but what with Katta?</p>
