Mitani was probably talking about PGCluster, not PGCluster -II. Mitani? Last time I heard about PGCluster-II was at Anniversary Summit(2006). Oh, and I met with him at France at 2007, and no improvements since then.

Yes. He will make a presentation about PGCluster at PGCon 2009 Japan. http://www.postgresql.jp/events/pgcon09j/e/program_2#10 Regards, -- Fujii Masao NIPPON TELEGRAPH AND TELEPHONE CORPORATION NTT Open Source Software Center -- Sent via pgsql-hackers mailing list (pgsql-hackers(a)postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
From: mitani on 17 Sep 2009 21:13 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.

From: Marcos Luis Ortiz Valmaseda on 17 Sep 2009 22:59 Excellent news,Mitani. My personal intention if to help you with this work for the redesign of PGCluster-II, or on the coding of it. If we work like a team, we can release this new version of the project more quickly. Do you have any sources repository of this new version? I work fine with CVS and Subversion but if you are working with Git, is better, because is my favorite SCM. Regards, and I'll be waiting your answer.

Mitani-San, thank you for this heads up on PGCluster-II. The partial data idea sounds very interesting and I'm looking forward to an inspiring meeting in Tokyo.
