Is Molecula Data Virtualization? 

People often think of data virtualization as being a layer on top of existing data access technologies — federating queries down to source systems, caching results, and providing a unified schema and language for the access of data. Molecula is a new take on Data Virtualization. FeatureBase answers queries without federating them down to source systems.

It stores the data in a fundamentally different way which is naturally compressed compared to the source representation and highly efficient for machine-scale analytical workloads. We consider our modern approach to data virtualization to more closely mimic the virtualization that we’ve seen in the industry, such as compute virtualization (vmware).
