[infinispan-dev] Distributed index?

Hi, as we've discovered some imperfections in current distributed index implementation, I'd like to know whether it could be possible to store on each node only index of those entries that are primary-owned on that node. Then, each query would be broadcast to other nodes and the results would be merged. From what I understood from Coherence documentation, they do that this way - this seems quite reasonable to me, and does not introduce any bottleneck as our index-master node (and also it does not require any synchronization on shared index). It's also different from sharding which introduces multiple indices but shares the index across nodes. I can easily imagine simple ... WHERE x = 'y' queries, ORDER BY or projections wouldn't be complicated either (unless sorting by non-projected field). Effective offsets and limits would require a bit more work, but the simplistic implementation (non-distributed merge) shouldn't be hard either. Could this approach be used with Lucene easily, or are there any caveats? Radim -- Radim Vansa <rvansa(a)redhat.com&gt; JBoss DataGrid QA
