Re: PGCluster-II Progress

I was searching info about PgCluster-II yesterday and there is not much information about it.
Do can give to me any report of this? Because I need to know the progress of the project.
On PgFoundry, only it talks about PgCluster-1.9, but not of the 2.x versions.

Who is the PgCluster-II´s developer?

I had the same question a while a go.
After a lot of googling I found http://www.cybertec.at/english/start_e.html
This seems to be an active replacement for the dead? pg-cluster

Odd, I talked to him a couple of weeks ago and he was working on a new
release in preparation for some upcoming talks he was doing ... was
working on bringing it up to support 8.3.x ...

"But, I'm just prepareing new version of the PGCluster..."

Mitani ... any status on this?

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.

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,

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.

Kind Regards
