Postgres has long been a database that easily scales vertically. It has also supported durable and reliable binary replication.
In the last two years, work on HA, clustering and extensions to our MVCC system has produced clustering features that help Postgres efficiently scale across many smaller systems.
This talk will start with a demo of the latest Postgres replication features. Then, we'll walk through open source and commercially-supported stacks that supporting the most demanding applications backed by Postgres.
In version 9.1, Postgres added streaming and synchronous replication that can be configured in about 5 steps. In 9.2 (to be released in 2012), we're adding cascaded replication and optimizations for common developer requests.
These features set the stage for a fast, efficient and distributed SQL cluster -- one that has configurable durability, is easy to administer and supported by "cloud" and virtualization vendors.
