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.
