This section describes the main functionalities from a end user point of view.
Hue consists in a single page interface that allow the users to perform data analyses without losing any context. The goal is to promote self service and stay simple like Excel so that 80% of the user can find, explore and query data and become more data driven.
1. Find or import your data
Use the left metadata assists to browse your existing data without losing your editor. The top search will look through your saved queries and matching tables, columns and databases. Objects can be tagged for a quick retrieval or assigning a more “humane” name. If the data does not exist yet, just drag & drop it to trigger the Create Table wizard and to import it in just two steps.
2. Query your data
When you found your data, the Editor’s autocomplete is extremely powerful as they support 90-100% of the language syntax and will highlight any syntax or logical error. The right assistant provides quick previews of the datasets, which columns or JOINs are popular and recommendations on how to type optimized queries. After the querying, refine your results before exporting to S3/HDFS/ADLS or downloaded as CSV/Excel.
Each app of Hue can be extended to support your own languages or apps as detailed in the developer guide.
