The upcoming version 1.6.1 of Barman will introduce a few interesting
new features which consolidate its central role in business continuity
installations of PostgreSQL databases. Discover why.
You now have time until March 14th, 2016 to submit your talk to "5432...MeetUs!", the conference
organised by 2ndQuadrant that will take place in Milan next June 28th and 29th.
Further information on the call for papers can be found on the conference website.
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 testing and benchmarking activities. If you are curious to know more about that process, please refer to the slides of that talk, which are publicly available on Prezi.
For the impatient: redislog taps into PostgreSQL's logging facility and allows DBAs to ship log events into a Redis queue, directly in JSON format, and to enter the ELK stack through the first class lane.
Devops and the (more…)
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 day, a very large basin of WAL files, collected from one or more PostgreSQL servers within the same organisation.
The internal codename of this feature was "WAL hub" and, in our mind, its main purpose was to allow any application (e.g. standby) to easily request and receive any WAL file for a given server, by enhancing Barman's command line interface and, ultimately, by implementing server support for PostgreSQL's streaming (more…)
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 established non profit organisation such as ITPUG (Italian PostgreSQL Users Group).
