PGConf.Russia 2021

Everyone knows very well what a failover cluster PostgreSQL is and how such a cluster protects against failures within the same data center. However, recently, more and more enterprises have placed increased demands on their services, these requirements include disaster tolerance. We call such clusters a GEO-Cluster (KUK). In the report, I will talk about the varieties, principles and approaches to building GEO-Clusters PostgreSQL based on the Corosync/Pacemaker cluster software.

Narrow way to four nines. Postgresql clusterin in virtual environment - why's and how's. Why Corosync/Pacemaker? What about backups? Difficulties, problems and how to avoid them.

Intel® Xeon® Scalable Gen 3 - new commands have been added to speed up the database: vector bit manipulation instructions to enable data compression without losses, vector instructions to make TLS protocols faster and SGX enclaves for secure code execution. We will also discuss the new generation of persistent memory Intel® Optane™ PMem 200 series. We will explain what these new technologies including oneAPI tools can give to the PostgreSQL project community

Throughout the release cycle of version 14, I had the opportunity to describe the accepted patches in articles dedicated to each of the five release commitfests. The first two articles on Postgres 15 also have some remarks on PostgreSQL 14. If you have read them, you can skip my presentation :-)). On September 30, 2021, PostgreSQL 14 was officially released. Nothing will change in this major release, so it's the right time for a final overview. However, presenting each and every new feature in a 45-min. talk isn't possible. That's why I will be sharing with you my personal top of version 14 innovations.
