Hyper Parser
In this article
Overview
You can use this Snap to parse Tableau extract (hyper) file and convert it into documents.
Prerequisites
Tableau Hyper 10.25 or later version.
To run the Tableau hyper Pipelines in a plex, you must set the environment or system property
TABLEAU_HYPER_LIBSto hyper (excluding hyper folder) where thejccis running.Tableau Hyper Snaps use Tableau Hyper API version 21.0.0.12982. You must have the Java Native Access (JNA) and shared libraries of the same API version for the respective Operating System on which you are running your Tableau Pipelines.

Example
Reading And Parsing Tableau Hyper Data
This example Pipeline demonstrates reading and parsing Tableau Hyper data using Tableau Hyper Formatter and Hyper Parser Snaps.
First, we configure the JSON Generator and CSV Generator Snaps to pass JSON and CSV data. Upon validation, we get the JSON and CSV data respectively in the output preview of the Snaps.

Next, we configure the Hyper Formatter Snap to transform the JSON and CSV output into hyper extract format. We configure two input views, json_data and csv_data—this creates target tables with the same names in the Hyper database of Tableau.
|
|
Next, we configure the Hyper Parser Snap to parse the transformed Hyper data into two tables, one each for json_data and csv_data. Upon validation, we get JSON and CSV outputs in the two output previews.

Finally, we configure two Mapper Snaps to transform the incoming JSON and CSV data. Upon validation, we get the output data for each format (JSON and CSV).
