Deploying PostgreSQL Cluster with Query Load Balancing and Monitoring Capabilities on Kubernetes

Kubernetes is an open source container orchestration platform for automating deployment, scaling and management of application containers. Nowadays, more and more applications are being deployed in containers on Kubernetes.

There are several solutions that can help us to run a PostgreSQL cluster on Kubernetes. However, these solutions don't provide query load balancing capability. In this talk, I will show you how to combine PostgreSQL Operator with Pgpool-II to deploy a PostgreSQL cluster with query load balancing capability on Kubernetes.

Monitoring is a very important part in production environments. Although Kubernetes provides a basic way to monitor the status of a PostgreSQL cluster, this is not sufficient for managing a PostgreSQL cluster in production. An important improvement of Pgpool-II 4.2 release is the ability to output more useful statistics of the PostgreSQL cluster. In this talk, I will describe how to monitor and visualize the PostgreSQL cluster statistics in Prometheus for extensive cluster monitoring.

Modern DWH with open-source PostgreSQL

PostgreSQL has a long history in DWH. Netezza, Redshift, and Greenplum have turned specific PostgreSQL releases into DWH solutions. Nowadays, with the trends in PostgreSQL towards performance improvements (better partitioning, better statistics, JIT Compilation, etc.) and advanced PostgreSQL extensions, like the Swarm64 Data Accelerator, you can create a forward-looking, no lock-in, versatile, and reliable DWH. This talk will cover the PostgreSQL and DWH trends and touch on key arguments for choosing open source PostgreSQL for DWH.

How to manage an open source HA RDBMS in a cloud environment

High availability solutions have become extremely popular in the past few years. They play a critical role in building reliable systems based on affordable hardware. In this presentation, we will pay attention to some of the subtle aspects of the design and maintenance of such systems. In addition, the issues of capturing changes on a HA cluster will be addressed.

The Catcher of WAL-G

What do we expect from a backup system? What makes a good backup system stand out? And, most importantly, how do you select the right tools for this process? When preparing backups, many pressing questions arise. In my talk, I will tell you a story of building a system for taking and verifying backups in one company. We will discuss the issues of choosing a tool for working with backups, adapting to changing realities, the problems of cloud storage, and the limitless possibilities of open-source collaboration. This talk will comprise the experience I gained in two years. You'll take the same journey, but much faster. Welcome aboard!
