Apache Drill with Tomer Shiran


“It’s a great world to be a developer in. If you’re a developer today, you have so many tools and so many options.”

Apache Drill is a schema­-free SQL query engine for Hadoop, NoSQL, and cloud storage. Drill is unique in that it uses a JSON data model instead of a relational model like many traditional engines. Additionally, it supports on-the-fly schema discovery, which allows execution to begin without knowing the structure of the data. As a result, Drill can work with data that is constantly updating or changing.

Tomer Shiran is the founder of the Apache Drill project and the CEO of Dremio.
