From Data Lake Entanglement to Data Mesh Decoupling: Scaling a Self-Service Data Platform

From Data Lake Entanglement to Data Mesh Decoupling: Scaling a Self-Service Data Platform

Geert Jongen
Data Lake Delta PySpark

Our data platform journey started with a classic data lake — easy to ingest, hard to evolve. As domains scaled, tight coupling across source systems, pipelines, and data products slowed everything down. In this talk, we share how we re-architected toward a domain-oriented data mesh using PySpark, Delta Lake and DQX to achieve true decoupling. Expect practical lessons on designing independent data products, managing lineage and governance, and scaling self-service without chaos.
