    PostgreSQL vs Redis: Making the Right Choice

    With the rise of NoSQL databases, a number of falsehoods have flourished regarding how to choose a database engine. This talk focuses specifically on Redis and PostgreSQL, and why one might choose one or the other.

    At small scales, we can often get by thinking of database servers as black boxes, but as we scale, the internals and architecture become more and more important. This talk focuses on behavior of these systems at scale and under load.

    In this presentation you will learn:

    • How Redis and PostgreSQL differ architecturally
    • How differences in architecture affect scalability and performance
    • Cases here Redis is the clear winner
    • Cases where PostgreSQL is the clear winner

    Additionally, some notes will be offered in terms of where PostgreSQL can improve in to compete with the sorts of workloads that generally favor Redis.

    Pgpool-II in the "Master-Master" mode or Network engineer’s overview of the PostgreSQL load balances solution.

    One of the main needs of high-load database projects is a right configured load balancer within the database cluster. Most of the solutions I worked with, including Pgpool-II, could not fully suit business requirements. In this article me as a network engineer with broad experience will cover tricky configurations of the Pgpool-II operating in the “Master-Master” mode, as well as consider cases in which similar solutions are indispensable.

    Heterogeneous distributed system - as a way to safely migrate from MSSQL Server to PostgreSQL, as well as reduce sanctions risks

    This report is primarily intended for companies, specifically their IT departments, that are running Russian systems 1C 8.x and have the ability to work with both MSSQL Server and PostgreSQL. We live in a unique time when having a heterogeneous IT system (a system with a distributed architecture where each database instance runs under different databases and/or has a different data structure) is justified both economically and in terms of potential risks. On the one hand, we store data and use databases with predictable behavior and open source code, regardless of the political situation. On the other hand, with this approach, we take advantage of all the benefits (primarily performance) of a powerful database supported by the largest vendor, albeit a hostile state to us. Now is the time to assess risks with the necessary level of paranoia. After all, data can be corrupted not only at the level of storage logic, but also by the method of additional "hidden" calls of Delete/Update constructs at the engine level of the database. Therefore, it is now relevant not only to monitor the performance of the IT system, but also to audit data and their timely integrity. It is necessary to implement data verification procedures, it is necessary to implement procedures for closing periods, procedures for fault-tolerant storage. And accordingly, to provide for various threat models in data recovery procedures. The report presents options for countering such threats and scenarios for the most seamless transition of large databases to PostgreSQL, since it is precisely for such databases that the problem of translating to a new DBMS is particularly acute.
