PGConf.Russia 2021

This talk is a brief overview of Intel technologies: CPU development, including features for AI algorithms. The memory speed/volume pyramid > PMem space, encryption development, software tools to improve parallel computing performance. I will also share a couple of cases where PG and Intel were implemented.

The development of secure system software (like an operating system or a DBMS) and ensuring trust in it are complicated scientific and technical tasks. In our presentation, we will demonstrate how we resolved these tasks for the Astra Linux OS certified to comply with the highest security classes. We will discuss the key directions of our activities, from the formation of national standards to the development and verification of the formal access model, which is the basis for the attack surface protection mechanism on the OS's level. We will also share how we apply the methods and technologies of dynamic and static analysis of the program code and, finally, we will explain how we collect and analyze the data we get from analyzing the OS code. We will also discuss how to fix the code errors in the project with continuous integration.

PostgreSQL maintenance without backups is unacceptable. The constant growth of PostgreSQL clusters in maintenance creates new issues and bottlenecks for the chosen backup scenario. In this presentation, we will explain how to efficiently use pg_probackup under such circumstances.

The pgpro_scheduler extension has an interesting but little-known feature - one-time jobs. Despite its simplicity, this feature can be used for complex transaction processing. On the one hand, it helps to reliably execute tasks taking a very long time, on the other hand, it ensures app scaling if certain conditions are met.
