Apache Drill is an open source SQL query engine for analysis of large-scale datasets. It allows for low-latency queries on data stored in Hadoop, such as files, HBase tables, and Hive tables. Drill supports ANSI SQL, schema discovery on-the-fly, and flexible data modeling to allow for analysis of semi-structured data like JSON. It aims to improve the distance to data for business users by enabling self-service data exploration using a familiar SQL interface.
