Hyper Formatter

Overview

You can use this Snap to convert the incoming documents into a Tableau hyper extract file and send the extract to the binary output view.

Note: This Snap requires additional time to convert a temporary CSV file into a Hyper Extract file. When the Snap processes a larger number of input documents, the time taken to generate the hyper file will naturally increase. This behavior is expected and is inherent to the functioning of the Snap.

Hyper Formatter

You can configure multiple input views in this Snap as the hyper file contains multiple tables. The table names for the hyper file is taken from the View Labels that you configure in Views.

Snap views

View Description Examples of upstream and downstream Snaps
Input Data in document format.
Output Document in binary format.
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 an error occurs.
  • 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.

Snap settings

Note:
  • 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 (Plus Icon): Indicates that you can add fields in the field set.
  • Remove icon (Minus 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 Required. 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
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.

Troubleshooting

"java.lang.UnsupportedClassVersionError"

The java.lang.UnsupportedClassVersionError error might be displayed when the JCC node contains a JDK version lower than 11.

Follow these steps to resolve this error:
  1. Define the /etc/sysconfig/jcc file on the node.
  2. Ensure that the JDK11 or a higher version is available as the first JAVA in the path environment variable. For example: 
    
                  JAVA11_HOME=/usr/java/<JDK Directory> 

                  PATH=$JAVA11_HOME/bin:$PATH 

                  export PATH
