I firmly believe that clustering support should be a part of Lucene. We've tried implementing it ourselves and so far have been unsuccessful. We tried storing Lucene indices in a database that is the back-end repository for our app in a clustered environment and could not overcome the indexing exceptions in our custom Directory implementation. I think it'd be perfect if some of the Lucene gurus were to implement an RDBMS-backed Directory and post it (in addition to the sleepycat.db package that's currently in contrib). The nitty-gritties of dealing with Lucene indexing structures at a single byte level are just way too much trouble to deal with for application integrator like myself. - Dmitry

Do you plan to release some kind of a commerical product including an API? I ask because I'm evaluating different technologies for a prototype which is part of my diploma thesis. The problem is that I have to deal with real huge data amounts and one machine is simply not enough to handle those amounts of data. Lucene seems to be a good choice but it won't scale up for real big data amounts. So I thought about expanding the indexes over several machines in junks so that it fits into the memory of those machines. One machine should collect the results and calculate some kind of score out of the delivered hits from the machines. As I'm not familiar with the concrete mechanisms of Lucene this is just a naive thought, but I think that such a clustering mechanism could become a killer app. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
