Apache Drill Query Optimization Training Course


7 hours (usually 1 day including breaks)


  • An understanding of Hadoop, NoSQL, and other data storage concepts
  • A general understanding of SQL queries
  • Experience with Linux command line


Apache Drill is a schema-free, distributed, in-memory columnar SQL query engine for Hadoop, NoSQL and other Cloud and file storage systems. The power of Apache Drill lies in its ability to join data from multiple data stores using a single query. Apache Drill supports numerous NoSQL databases and file systems, including HBase, MongoDB, MapR-DB, HDFS, MapR-FS, Amazon S3, Azure Blob Storage, Google Cloud Storage, Swift, NAS and local files. Apache Drill is the open source version of Google’s Dremel system which is available as an infrastructure service called Google BigQuery.

In this instructor-led, live training, participants will learn how to optimize and debug Apache Drill to improve the performance of queries on very large data sets. The course begins with an architectural overview and feature comparison between Apache Drill and other interactive data analysis tools. Participants then step through a series of interactive, hands-on practice sessions that include installation, configuration, performance evaluation, query optimization, data partitioning, and debugging of an Apache Drill instance in a live lab environment.

By the end of this training, participants will be able to:

  • Install and configure Apache Drill
  • Understand Apache Drill’s architecture and features
  • Understand how Apache Drills receives and executes queries
  • Optimize Drill queries for distributed SQL execution
  • Debug Apache Drill


  • Developers
  • Systems administrators
  • Data analysts

Format of the course

  • Part lecture, part discussion, exercises and heavy hands-on practice
