PGConf.Russia 2021

Postgres has been a vibrant project for decades, and probably will be popular for decades to come. However, as with any complex endeavor, challenges are always lurking. This talk explores the many project, competitive, and technical challenges in the future that could derail its success. By exploring these challenges, we will be better able to avoid them.

Data is getting bigger, disks are getting faster, the DBMS optimizer is getting smarter, but the problem of " bloating " remains extremely relevant. I want to share my experience and approach to dealing with this effect on a large number of tables and data in them.

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.

TimescaleDB extension allows to turn good old Postgres into a real distributed cluster for storing time series data while maintaining the relational model, convenient SQL and a time-tested ecosystem. And additional features such as continuous materialized views and data compression allow to build truly powerful telematic hubs.
