Accessing large data sets with Direct Discovery
Direct Discovery expands the associative capabilities of the Qlik Sense in-memory data model by providing access to additional source data through an aggregated query that seamlessly associates larger data sets with in-memory data. Direct Discovery enhances business users’ ability to conduct associative analysis on big data sources without limitations. Selections can be made on in-memory and Direct Discovery data to see associations across the data sets with the same Qlik Sense association colors - green, white, and gray. Visualizations can analyze data from both data sets together.
Data is selected for Direct Discovery using a special script syntax, DIRECT QUERY. Once the Direct Discovery structure is established, Direct Discovery fields can be used along with in-memory data to create Qlik Sense objects. When a Direct Discovery field is used in a Qlik Sense object, an SQL query is run automatically on the external data source.
