In this article, eWeek provides a great insight of Dremio, the Data-as-a-Service platform. This is a great takeaway:
“Where Dremio breaks new ground, and makes Data-as-a-Service a meaningful new idea, is in taking responsibility for delivering high-performance queries on heterogeneous sources, in addition to these other capabilities. In some other products, the whole idea is to use the system to allow the right extract of data to be retrieved and used in some way by a single analytics tool or an application. With Dremio, high performance is available to all tools.”
