How can hundreds of in-store applications adapt instantly to the specificities of a country, a sport, or even a single user, without any code deployment? This is the challenge we took on with**Paramethor**.

In this presentation, we will look back at the genesis of this product, born from a critical need at Decathlon: **reducing Time-to-Market** (TTM) and avoiding the sprawl of configuration databases. We will explore how we built a robust solution consisting of a high-performance backend, an intuitive admin interface, and a real-time notification system via Kafka to inform applications of every change.

We will dive into the technical heart of the rules engine, specifically our **prioritized** search strategies. You will discover how we manage the complexity of business contexts (Store, UID, Country, third-party type, etc.) to offer extreme granularity in controlling features and configuration values.

**Key points covered :**
* **Why ?** Shifting from rigid configuration to total autonomy for both business and technical teams.
* **How ?** Technical architecture, exception management, and conflict resolution strategies based on priority.
* **Impact :** Reducing operational costs, securing deployments, and accelerating In-Store innovation.
