This keynote presentation from Data Council explores the evolution of the deconstructed database vision and the emergence of open data lakes. Julien Le Dem, Principal Engineer at Datadog, draws on years of experience to explain how the big data ecosystem has transformed into a composable architecture built around open source standards. Discover how to leverage interoperable components such as Parquet, Arrow, and Iceberg to create flexible data systems while avoiding vendor lock-in. Particularly valuable for system architects designing data infrastructure or engineers developing specialized query engines, this talk provides strategic insights into building modern, standards-based data architectures that maintain freedom of choice in your technology stack.
