I'm sorry for late my response. I already sent same contents to Marcos, but I did not cc to all of yours. (I'll join pgsql-hackers ML).
1. Statement of PGCluster-II The state of PGCluster-II is re designing. I developed and demonstorated PGCluster-II as full data shared model in 2006. It worked fine. However, perfomance point of view, it was not good at all. Then, I improved it in 2007. Even so, it was absurdly slow. I think that it was required redesigning to improve performanse. The full data shread model is not difficult to build up (I developed the 1st PGCluster-II within 2 weeks), but it is not easy to improve performanse. Then, I chose partial data shared model as my conclusion. I spend two years to decide it. 2. Prospects of PGCluster-II Currentry, I'm developing the cluster server management tools as a part of the latest PGCluster. It will be upcoming release. After that, I will be back to the PGCluster-II project. On comming Nov. 19, The International PostgreSQL Cluster Developper's Meeting (I'm not sure the proper name) will be held in Tokyo. I'll discuss about a task of PGCluster-II as a part of PostgreSQL's cluster project at the meeting. Clustering is getting more important each day. I'm expecting that PGCluster & PGCluster-II play a role in the solution. Best regards, ------------------- At.Mitani -- original message -- From: Devrim G？ND？Z<[email protected]> To: Marc G.
