How Leroy Merlin France Replaced Airflow and Built a Data Mesh at Scale

Leroy Merlin France, a subsidiary of ADEO Group managing data operations for 80,000+ employees across 140 stores, needed to replace a fragmented legacy scheduling stack and a failing Airflow deployment with a platform that could support self-service data engineering at scale. Starting in May 2020, they built a full DataOps lifecycle on Kestra: GitOps deployment, a custom ingest plugin, Enterprise RBAC, and a Data Mesh architecture where individual squads publish their own data products. Today the platform orchestrates 5,000+ flows, serves 250+ active engineers, and has been a cornerstone of LMFR's data operations for over six years.

"Kestra is the unifying layer for our data and workflows. You can start small, but then there is no limit to the possibilities and scalability of such an open architecture."
