Modern data is often messy and does not fit into the old schema-on-write or even the newer schema-on-read paradigms. Some data effectively has no schema at all. For example, in a MongoDB collection or a Mixpanel log file, different records may have different fields, and identically named fields in different records may have different types. This can make doing any sort of analysis extremely difficult.
Apache Drill has been built with this sort of data in mind. Tomer Shiran explores how to analyze such data with Drill, covering Drill’s internal architecture and explaining how type introspection can be used to query JSON and JSON-structured data—such as data in MongoDB—without requiring a schema.
