Alexey Ignatov PostgresProTo migrate to a PostgreSQL/Postgres Pro we need multi-core servers to be carefully tuned for correct parallelism. What settings make multi-terabyte installations work fast and correctly?
We will share our PostgreSQL/Postgres Pro on BullSequana S and Bullion S servers testing experience.
- The features of this hardware platform which are crucial for high-loaded configurations
- Multi-core Scale-up servers and PostgreSQL/Postgres Pro
- Results of stress testing of PostgreSQL/Postgres Pro running on the equipment.

Nikolay Samokhvalov Nombox LLCShared_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How can we ensure that this – pretty much outdated – recommendation suit well our needs?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:
- comprehensive database experiments, conducted in automated fashion, repeated multiple times in conditions as close to production as possible, and
- 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.

Aleksander Pavlov ModulbankAs any ordinary software developers, we just pursued a goal to develop a system robust for high loads, and even succeeded. The system architecture was fine, but the data volume was keeping increased and revealed the painful issues and errors that nobody had expected. We faced very strange queries seemed to be unbelievable. In my short talk I would like to share sad experience of arised-from-nothing high loads in DBMS and solving the challenge.
