postgres-xc-developers Mailing List for Postgres-XC

Benny,

An additional comment-

In the source code, most of the changes compared to PostgreSQL are below 
src/backend/pgxc. These are all new files. You can look through and read 
comments.

In addition, changes to existing PostgreSQL modules can be easily found 
by searching for the string PGXC, so you can see what changed and why.

Thanks,

Mason

Benny,

There was a talk we gave at PG con in Ottawa in May. In the presentation 
slides was some additional info about upcoming features. There is some 
audio here: http://www.pgcon.org/2010/schedule/events/226.en.html.

The amount of SQL coverage has expanded greatly compared to when we 
first announced the project, and the current development head adds even 
more, if you want to download that.

HA is currently being designed and discussed so you can expect to see 
that in the future.

If it fits in with your post-graduate work, please feel free to get 
involved and contribute to the project.

Regards,

Mason

Dears:
     I've learned much about postgres-xc recently. I am very interested in its "architecture". I want do some experiments based on it for my postgraduate paper.
     By reading the documents and source code, I found it will be a long time from postgres-xc stability and high performance. For example, there's no any HA(High-Availability) solution such as standby during the cluster running. In addition, many statements are not supported in postgres-0.9.2-release.You will be greatly appreciated if you could tell me something about postgres-xc recent and future development schedule. According to that, I can make an appropriate experiment plan. It’s a little bit urgent, thank you for your reply. I will always keep eyes on our postgres-xc.
                                                                          Yours truly,
                                                                               Benny
 


      

Benny,

Thank you very much for the suggestion.    Yes, I understand the README is
not rich.   Instead, we have "architecture" document which you can download
separately, as well as other manual and guidelines.

Could you try these documents?   Especially, I made "architecture" document
as a separate one because XC internal is not simple to understand and I
thought usual document with graphics and tables will be more helpful.

Your advice is very valuable.   I'll be waiting for your further advice.

Thank you very much;
