Hi, Just FYI... Boris Lublinsky released a new article that starts to talk about a PoC we did earlier in the year.
Without spoiling the article, the reason I wanted to point this out is that there have been a couple of posts around the community (including some of the social networking sites...) where people are presenting Hadoop only being good for batch processing while ignoring that you can use it for real time applications. Using HBase as a backing store to Lucene appears to be a valid option. If you are bored, or really are interested in a HBase use case... Check out http://www.infoq.com/articles/LuceneHbase -Mike PS. Going from memory, this is the first of 3 articles on the topic.... Sent from a remote device. Please excuse any typos... Mike Segel
