Apache Drill is an open source, schema-free SQL query engine—that enables a business to extract the most value possible from data stored in Hadoop. Apache Drill does this by breaking down many of the technical barriers that had restricted the ways that analysts could work with data, and limited the intelligence that they could glean from it. With Apache Drill, data scientists are no longer constrained by the limitations of last generation tools, and they are free to work with data in a myriad of productive ways without draining IT resources.
