Furthermore, it also provides multimaster capabilities; this means that changes made in either the primary or secondary node will appear in both copies of a replicated table.

There is something to be said for tools that encourage simplicity when maintaining a complex high availability architecture. Let's explore Bucardo further.

Getting ready

The latest stable version of Bucardo at the time of writing this book is 5.4.1. Obtain the latest source package from the following URL:

https://bucardo.org/wiki/Bucardo

Bucardo is written in Perl, so it requires quite a few Perl-based prerequisites. On Debian-based systems, install them using the following apt-get commands:

sudo apt-get install libdbix-safe-perl libdbd-pg-perl libboolean-

Shaun Thomas

Shaun M. Thomas has been working with PostgreSQL since late 2000. He is a frequent contributor to the PostgreSQL Performance and General mailing lists, assisting other DBAs with the knowledge he's gained over the years. In 2011 and 2012, he gave presentations at the Postgres Open conference on topics such as handling extreme throughput, high availability, server redundancy, and failover techniques. Most recently, he has contributed the Shard Manager extension and the walctl WAL management suite. Currently, he serves as the database architect at PEAK6 Investments, where he develops standard operating procedure (SOP) guidelines to facilitate reliable server architecture among many other tasks. Many of the techniques used in this book were developed specifically for this extreme environment. He believes that PostgreSQL has a stupendous future ahead, and he can't wait to see the advancements subsequent versions will bring. https://www.linkedin.com/in/bonesmoses
