Synopsis
This operator can write an ExampleSet to Tableau Hyper (.hyper) file.Description
Hyper is Tableau's in-memory Data Engine technology optimized for fast data ingest and analytical query processing on large or complex data sets. Beginning in Tableau 10.5, new extracts use the .hyper file format instead of the .tde file format.

Output
