Consensus, Postgres, Multimaster

Postgres Pro Multimaster is Postgres extension (and a set of core patches) providing high availability (HA) with strong consistency and read scalability. It forms symmetric shared-nothing cluster synchronously replicating the data and automatically performing disaster recovery. During the last year we've put significant efforts ensuring and proving that consistency is preserved in all scenarios. The new version, which will be released as part of Postgres Pro Enterprise 13 uses Paxos algorithm for determining transaction outcome and custom protocol governing the recovery process; we used TLA+ model checker to verify its correctness. I'll tell how these things work and why in some cases multimaster may be an attractive alternative to the traditional streaming replication based HA deployments.

multimaster is now open source, available at https://github.com/postgrespro/mmts

To make the talk less narrow specialized and more appealing to the wide audience, in the first part I will shed some light on how generally modern DBMSs (mostly so-called NewSQL) handle fault tolerance. In particular,

what is a strongly consistent DBMS and the associated overhead;
what is distributed consensus, Paxos, Raft;
how they help here;

I won't do an attempt to explain any algorithms line-by-line; it would be hardly useful given the time frames and there is a lot of literature available anyway. The goal is rather to waymark the field and get you a bit comfortable there.

Postgres Architectures in Production

When using PostgreSQL in production it is important to implement a strategy for High Availability. With a database service, the HA properties apply to both the service itself and of course to the data set.

In this talk we learn how to think about specific HA needs of your production environment and how to achieve your requirements with Open Source tooling when it comes to your database of choice, PostgreSQL. In particular, we dive in many options that could be implemented for Postgres to evolve its offering from being a toolset to being “batteries included”. What does it mean in the context of HA? How to achieve it?

Conferences like this give people a personal feeling for the software. You can understand why people are passioned about it. They get confidence in using it and confidence that the software is gonna be around for a long time. The conference has people who is responsible for and designing Postgres. And I really think it excites to continue using Postgres.

This is a very technically oriented conference. There is a lot of knowledge sharing happening. A lot of really talented people. And it is also for us a great opportunity to tap into the Russian market, a very interesting market for Postgres.
