In an Open Data Infrastructure, data moves freely, and the different elements of the data stack can be tailored as needed for specific use cases. The keystone of the Open Data Infrastructure is the modern data lake, because the combination of open table formats and commodity storage decouples compute and storage. [CTA_MODULE]“Open standards” doesn’t mean “open source” (and that’s ok)Open standards and open source are orthogonal concepts and can comfortably coexist. dbt Core, an open source tool, is a good example of an open source system that can be leveraged within an Open Data Infrastructure alongside proprietary systems such as Fivetran. Pitfalls that close your data infrastructureAn Open Data Infrastructure must be modular, commercially portable, and context-rich.
