Topic: Clustered PostgreSQL Databases

Introduction & Description of Talk:

This talk will provide a brief overview of PostgreSQL Clustering, but will primarily focus on Postgres-XC, an open-source write-scalable, clustered database project.

Postgres-XC (eXtensible Cluster) is a multi-master write-scalable PostgreSQL cluster based on shared-nothing architecture, developed by Postgres-XC Development Group.

   Wikipedia Articles on Databases:


Mason Sharp is co-founder and CTO of StormDB. Mason has had a passion for RDBMS systems and data management since he was a university student. Mason developed a parallel distributed MPP database system targeted towards data warehousing called ExtenDB, which was folded into EnterpriseDB as GridSQL in 2007. He also recently helped architect Postgres-XC, a shared-nothing database system targeted for write scalability and which makes for one of the key technological underpinnings of StormDB.


StormDB is a cloud services company based on the Jersey Shore in Red Bank, NJ. We are passionate about making powerful yet simple to use distributed databases. All too often developers need to make trade-offs to balance scalability, reliability and cost for their database needs, but we believe that they don't need to, they just haven't had the right solution yet. StormDB's unique cloud utility model around a large scale relational database cluster gives developers the solution they really need. Simplicity, reliability, scalability without busting your budget.


Addison-Wesley Professional/Prentice Hall PTR, and O'Reilly have been kind enough to provide us with review copies of some of their books, which we will continue to raffle off as giveaways at our meetings. The publishers always ask that the persons receiving the books provide a review and/or feedback about their books.

Unigroup would like to thank both companies for the support provided by their User Group programs.

As always, all of the books will be available for review at the start of the meeting.

We have some Solaris Related CD-ROMs from our friends at the local NYC Sun Microsystems Office.

(Note: Our supply of books is low right now, we hope to resolve that soon.)


Unigroup is a Professional Technical Organization and User Group, and its members pay a yearly membership fee. For Unigroup members, there is usually no additional charges (ie. no meeting fees) during their membership year. Non-members who wish to attend Unigroup meetings are usually required to pay a "Single Meeting Fee".

         Yearly Membership (includes all meetings):      $ 50.00
         Student Yearly Membership (with current! ID):   $ 25.00
         Non-Member Single Meeting:                      $ 20.00

       * Payment Methods: Cash, Check, American Express.

       ! Students: We are looking for proof that you are
         currently enrolled in classes (rather than working
         full-time), and as such, your Student ID should show
         a CURRENT date.  We have been presented Student IDs
         containing NO dates whatsoever, and in the
         current environment, perpetual/non-expiring access
         to university facilities just does not feel right.
         If your ID contains no date, please bring
         additional proof of current enrollment.  Thanks.

NOTE: Simply receiving Unigroup Email Announcements does NOT indicate membership in Unigroup.

Members: Remember to bring your membership card with you to the meeting, to confirm your yearly renewal date!
