More details about the talks:

• MobilityDB: Bringing Mobility Data Inside PostgreSQL
  MobilityDB is an open source data management and analytics platform for mobility data (https://github.com/MobilityDB/MobilityDB). Its core function is to efficiently store and query mobility tracks such as vehicle GPS trajectories. Built on top of PostgreSQL and PostGIS, it provides spatiotemporal data management via SQL.
  Because it is implemented as a native PostgreSQL extension, MobilityDB can be deployed in traditional on premise setups as well as cloud and edge environments without requiring a separate data platform.
• Scaling Semantic Models: Bespoke PostgreSQL Schemas at SaaS Scale
  While most CMS platforms rely on generic EAV tables, ContentGrid generates native PostgreSQL schemas directly from user-defined semantic models. We’ll discuss the challenges of automating DDL migrations for thousands of unique schemas and the infrastructure patterns we use to keep this model-driven approach performant, isolated, and manageable at scale.
• Percona Operator for PostgreSQL: An Honest Overview
  In this talk, we review the Percona Operator for PostgreSQL, how it derives from its Crunchy foundation, how it is architected, and the capabilities it provides. We will examine its strengths and weaknesses, how it approaches vendor lock in, and the strategy shaping the project.
  The goal is not to present a feature list or a how to guide, but to focus on architectural considerations and operational tradeoffs.

We’re looking forward to another great evening of PostgreSQL, community, and good conversations in Brussels.
See you there! 🐘💛🖤❤️
