During the last October’s Italian PGDay and European PostgreSQL conference, my friend Marco Nenciarini and I had the pleasure to talk about a new open source plugin for PostgreSQL, called redislog. In that presentation (“Integrating PostgreSQL with Logstash for real-time monitoring”) we provided an example of our exploration/experimentation approach, with extensive and thorough coverage of […]
Barman 1.5.0 enhances the robustness and business continuity capabilities of PostgreSQL clusters, integrating the get-wal command with any standby server’s restore_command. In this blog article I will go over the reasons behind this feature and briefly describe it. One of the initial ideas we had in mind when conceiving Barman was to make it, one […]
Today version 1.4.0 of Barman has been officially released. The most important feature is incremental backup support, which relies on rsync and hard links and helps you reduce both backup time and disk space by 50-70%.
PostgreSQL 9.4 introduces a new statistic in the catalogue, called pg_stat_archiver. Thanks to the SQL language it is now possible, in an instant, to check the state of the archiving process of transactional logs (WALs), crucial component of a PostgreSQL disaster recovery system.
November 7th 2014 was the eighth Italian PostgreSQL Day, the national event dedicated to the promotion of the world’s most advanced open source database. The Italian edition is one of the most enduring in the whole Postgres community (the first one took place in July 2007) and the results of the activity of a very […]
“Ooooh that smell! Can’t you smell that smell?“. That’s a classic rock song by legends Lynyrd Skynyrd, I know. But also a warning that your new Barman 1.3.3 installation can now emit.
With every new release, PostgreSQL gets better at addressing the needs of developers, database and system administrators. If you are part of a dynamic business that delivers high quality products or services, Postgres is a candidate technology for managing your databases (in case you have any).
In a previous blog post, I have gone through the steps of setting up a basic CentOS 6.4 64bit Linux distribution using Vagrant on your Ubuntu 12.04 LTS Linux. We will continue digging in the devops culture/movement and finally setup PostgreSQL 9.3 using Puppet in a local virtual machine.
My top #1 open source tool that I have discovered in the last year is definitely Vagrant. Vagrant is a software that helps you build and configure virtual environments for development and testing purposes. Vagrant relies on virtual machine providers such as VirtualBox, VMWare and AWS, as well as provisioning tools such as Chef and […]
The traditional Monash University Prato Centre, historical venue of the first European PGDay, will host the first edition of another conference: Open Source Software for Business, aka OSS4B. OSS4B 2013 will take place in Prato, Tuscany, Italy on September 19 and 20. Through the experience gained with several organisations of PostgreSQL related events, we have […]
