    Shared_buffers = 25% – is it too much or not enough? Or it's the right value?

    How can we ensure that this – pretty much outdated – recommendation suit well our needs?

    It is time to start apply enterprise-level approach to tuning postgresql.conf. Not using various blind auto-tuners or advices from old articles and blog posts, but based on the following two aspects:

    1. comprehensive database experiments, conducted in automated fashion, repeated multiple times in conditions as close to production as possible, and
    2. deep understanding of DBMS and OS internals.

    Using Nancy CLI (https://gitlab.com/postgres.ai/nancy) we will consider a concrete example: infamous shared_buffers, under various circumstances, in various projects. We will try to figure out, how to optimize this settings for given infrastructure, database, and workload.

    While doing development of one of our project we were asked to build HA database using Postgres, geographically distributed.

    First our choice was obvious, we started to work with big 3 cloud providers, but soon it was quite understand that everything costs big enough for us. Also there were a bunch of incompatibilities with unsupported extensions as well as londiste replication we were heavily used.

    I will talk about why we chose patroni, what types of problem we faced with and patroni's special features can dramatically simplify deploy and everyday usage.

    In this tutorial we will discuss Binary and Logical replication in a practitioner format. The topics that will be included are native Postgres replication technologies, configuring and managing them. We will also discuss performance and draw backs of various architectures (sync vs async etc...). At the end of this presentation the attendees will be able to configure a basic replication deployment with HOT Standby and well as have an understanding of other technologies such as Point in Time Recovery and cascading replication.

    Brendan Gregg’s USE (Utilization, Saturation, Errors) method for monitoring is quite known. There’s also Tom Wilkie’s RED (Rate, Errors, Durations) method, which is suggested to be better suited to monitor services than USE. I want to talk about how we employ these methodologies when we develop our Postgres monitoring in okmeter.io.
