Unless you were in Sydney for linux.conf.au 2018 last week you probably didn’t see my talk Geographically distributed multi-master replication with PostgreSQL and BDR. Luckily for you it’s on archive.org and YouTube. If you’re interested in multi-master replication of any sort, even non-PostgreSQL-based multi-master, it should be worth taking a look. The talk could’ve been […]
1. Introduction Postgres-BDR (or just BDR, for short) is an open source project from 2ndQuadrant that provides multi-master features for PostgreSQL. Here we will show how to build a test environment to play with BDR and how to configure it using the OmniDB 2.1 web interface. 2. Building test environment Let’s build a 2-node test […]
Postgres-BDR is an open source project from 2ndQuadrant that provides multi-master features for PostgreSQL. We have pursued a joint strategy of providing both working code available now and also submitting the features into core PostgreSQL. Postgres-BDR 1.0 runs on a variant distro of PG9.4. This is in Production now and receives regular maintenance and security […]
The BDR and pglogical apt repository GnuPG signing keys have been renewed. Users should re-import the existing keys. You can verify that it’s still the same key as referenced in the documentation, just with a later expiry date. Simply run: wget –quiet -O – http://packages.2ndquadrant.com/bdr/apt/AA7A6805.asc | sudo apt-key add – sudo apt-key finger AA7A6805 | […]
BDR is both a patch to PostgreSQL core and an extension on top of PostgreSQL core. How did that come about, and what’s it’s future? Development of BDR was initiated around the time PostgreSQL 9.2 was in development. Arguably earlier if you count things like the extension mechanism. The goal of BDR is, and has […]
I’m pleased to say that Postgres-BDR is on its way to PostgreSQL 9.6, and even better, it works without a patched PostgreSQL. BDR has always been an extension, but on 9.4 it required a heavily patched PostgreSQL, one that isn’t fully on-disk-format compatible with stock community PostgreSQL 9.4. The goal all along has been to […]
I was in Jakarta a couple of weeks ago and there happened to be a meetup of the Indonesia PUG in Bandung while I was there. Because it is just a 2 hour, rather picturesque drive, from Jakarta, I thought it was too good of an opportunity to miss. So I showed up. The meetup was hosted […]
The right answer is of course “Use PostgreSQL”. It’s the main distro and we want you to use that as often as possible. The Postgres-BDR and Postgres-XL projects are also fully open source projects, using the same copyright and licence as the main PostgreSQL project. So if you’re using PostgreSQL, they are also options to […]
Postgres-BDR has now reached 1.0 production status. Over the last 2 years, Postgres-BDR has been used daily for mission critical production systems. As you might imagine, it’s been improved by both bug fixes and feature enhancements that allow it to be used smoothly, so its mature, robust and feature-rich. The BDR Project introduced logical replication […]
I’m pleased to say that we’ve just released Postgres-BDR 1.0, based on PostgreSQL 9.4.9. This release contains significant improvements to DDL replication locking, global sequences, documentation, performance, and more. It also removes the deprecated UDR component in favour of
