Cleaning the data lake without drowning: A PM & DataOps story
FILLING

🤖 DATA/AI ARENA
Limited Capacity filling up
Storage is often treated as an infinite, invisible commodity, until the bill explodes or the Data Lake turns into a swamp. At Decathlon's scale, managing storage isn't just an infra topic; it's a **Product** that requires strategy, value measurement, and a serious cleanup.

In this session, **Lucie** (Senior PM) and **Soufian** (DataOps Engineer) share their unfiltered journey of reclaiming control over their storage zones. From the first discovery interviews to the automated deletion of Petabytes of data, they’ll reveal how they teamed up to turn a growth crisis into a sustainable efficiency model.

In this session, they will provide a deep dive into the practical synergy between:
- **Product Management for Infra**: How to apply PM frameworks to technical topics like storage costs.
- **The DataOps Engine**: A look under the hood of their automated cleanup stack (S3 Lifecycle, Delta Vacuum) and how they mitigated risks.
- **Cultural Shift**: How they moved from "keep everything" to "smart archiving" by design, proving that deleting is also delivering.

Whether you're a PM or a Dev, you'll leave with concrete tips on how to apply Product methodology to technical debt and ensure your Data Lake stays healthy and ready for the AI era.
