    Postgres Architectures in Production

    When using PostgreSQL in production it is important to implement a strategy for High Availability. With a database service, the HA properties apply to both the service itself and of course to the data set.

    In this talk we learn how to think about specific HA needs of your production environment and how to achieve your requirements with Open Source tooling when it comes to your database of choice, PostgreSQL. In particular, we dive in many options that could be implemented for Postgres to evolve its offering from being a toolset to being “batteries included”. What does it mean in the context of HA? How to achieve it?

    PostgreSQL Network Filter for EnvoyProxy

    How do you monitor Postgres? What information can you get out of it, and to what degree does this information help to troubleshoot operational issues? What if you want/need to log all the queries? That may bring heavy trafficked databases down.

    At OnGres we’re obsessed with improving PostgreSQL’s observability. So we worked together with Tetrate folks on an Envoy’s Network Filter extension for PostgreSQL, to provide and extend observability of the traffic inout a cluster infrastructure. This extension is public and open source. You can use it anywhere you use Envoy. It allows you to capture automated metrics and to debug network traffic. This talk will be a technical deep-dive into PostgreSQL’s protocol decoding, Envoy proxy filters and will cover all the capabilities of the tool and its usage and deployment in any environment.

    Postgres Pro Data Compression (CFS) for 1C ERP platform data

    Postgres Pro Enterprise has a great compression engine. The year 2020 was devoted to the study of this mechanism in the real work of 1C. We have accumulated some statistical data and of course the subtleties of the use and behavior of 1C compared to other popular DBMS, which I want to share.

    What's next in Logical Replication?

    Logical replication has been there since 10.0 and with each release, it is getting better. This talk will start with the basic architecture of Logical replication in PostgreSQL and then cover the various ways in which it can be helpful to users.

    One of the shortcomings of logical replication as compare to physical replication is that currently, it allows the transaction to be replicated only once it is committed. This can create a large apply lag on the subscriber side for long-running transactions. We will discuss the solution implemented for this problem for PostgreSQL.

    We will also discuss the other major work being done in logical replication which is to allow the streaming of transactions at the prepare time. This will help us in implementing conflict-free logical replication. This can be used for scaling-out reads as well. Because of 2PC, we can ensure that on subscribers we have all the data committed on the master. Now, we can design a system where different nodes are owners of some set of tables and we can always get the data of those tables reliably from those nodes, and then one can have some external process that will route the reads accordingly.

    In the end, this will cover the new enhancements, improvements related to Logical Replication in recent PostgreSQL releases.
