Hyper Parser

Overview

You can use this Snap to parse Tableau extract (hyper) file and convert it into documents.

Prerequisites

Tableau 10.5 or later version.
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 run your Tableau pipelines. Here are the downloadables of Hyper APIs. Download and extract the zip file for the specific operating system:
To run the Tableau hyper pipelines in Groundplex, you must set the environment or system property TABLEAU_HYPER_LIBS to /home/lib (excluding /hyper) where the JCC is running.
Install Tabcmd Utility and Tableau Hyper Library. Learn more:
- Install and configure tabcmd and Tableau Hyper Library on Linux
- Install and configure tabcmd and Tableau Hyper Library on Windows

Limitations and known issues

None.

Output	Document in binary format.	Mapper Copy
Error	Error handling is a generic way to handle errors without losing data or failing the Snap execution. You can handle the errors that the Snap might encounter when running the pipeline by choosing one of the following options from the When errors occur list under the Views tab. The available options are: Stop Pipeline Execution Stops the current pipeline execution when the Snap encounters an error. Discard Error Data and Continue Ignores the error, discards that record, and continues with the remaining records. Route Error Data to Error View Routes the error data to an error view without stopping the Snap execution. Learn more about Error handling in Pipelines.

Suggestion icon (): Indicates a list that is dynamically populated based on the configuration.
Expression icon (): Indicates whether the value is an expression (if enabled) or a static value (if disabled). Learn more about Using Expressions in SnapLogic.
Add icon (): Indicates that you can add fields in the field set.
Remove icon (): Indicates that you can remove fields from the field set.


Field / Field set	Type	Description
Label	String	Required. Specify a unique name for the Snap. Modify this to be more appropriate, especially if there are more than one of the same Snap in the pipeline.
Schema Name	String/Expression	Specify a schema name for the Tableau extract. If this field is left blank, the Snap uses the default schema Extract. Default value: Extract Example: DemoSchema
Routes	Required. Use this fieldset to define table names and the output views to send documents. You must specify each route in a separate row.
Table Name	String/Expression	Specify a name for the hyper table. Note: A table must exist in the incoming data of the hyper file. Else, an error is displayed upon validation. Default value: N/A Example: employees_table
Output view name	Dropdown list	Specify a name for the output view to which the documents should be routed. Default value: output0 Example: employees_table
Snap execution	Dropdown list	Select one of the three modes in which the Snap executes. Available options are: Validate & Execute. Performs limited execution of the Snap and generates a data preview during pipeline validation. Subsequently, performs full execution of the Snap (unlimited records) during pipeline runtime. Execute only. Performs full execution of the Snap during pipeline execution without generating preview data. Disabled. Disables the Snap and all Snaps that are downstream from it.
