Miscellaneous Configuration

This section contains miscellaneous configuration topics to enable minor features of the platform.

Limits

For more information, see Configure Application Limits.

Supported Extensions

By default, the Designer Cloud Powered by Trifacta® platform will allow you to upload any file. However, the platform may not be able to process some of them, as the list of supported file extensions is limited. For more information, see Supported File Formats.

When you upload a file with an unsupported file extension, a warning is displayed, and the file may fail to load in the Transformer page. 

As needed, you can add extensions to the list of supported file formats, so that no warning is displayed when a file of the specified type is imported. 

• Extensions are case-sensitive. .xml and .XML must both be listed.
• A leading period is required.

Steps:

1. You can apply this change through the Admin Settings Page (recommended) or trifacta-conf.json. For more information, see Platform Configuration Methods.

2. Locate the following parameter and add file extensions. In the example, two new extensions have been added to the list:

   "webapp.client.additionalAllowedFileExtensions": [".log",".LOG"],

3. Save your changes and restart the platform.

Feature Flags

Disable parameterization

By default,  Designer Cloud Enterprise Edition supports the application of parameters to imported datasets. Datetime, wildcard, or variable parameters can be used to operationalize execution of jobs on different versions of the same dataset. For example, if a new dataset is dropped in the same folder each day with a different date value in the filename, you can apply parameters to the imported dataset to ensure that all matching datasets in the directory can be executed. For more information, see Overview of Parameterization.

To disable this feature, please complete the following steps.

Steps:

1. You can apply this change through the Admin Settings Page (recommended) or trifacta-conf.json. For more information, see Platform Configuration Methods.

2. Set the following parameter to false:

   "feature.parameterization.enabled" : false,

3. Save your changes and restart the platform.

Disable target schema matching

By default,  Designer Cloud Enterprise Edition enables you to create target schemas for each recipe in your dataset. These schemas are represented in the Transformer page as a panel above the column headers. For more information, see Overview of Target Matching.

If you prefer to disable this feature, please complete the following steps.

Steps:

1. You can apply this change through the Admin Settings Page (recommended) or trifacta-conf.json. For more information, see Platform Configuration Methods.

2. Set the following parameter to false:

   "feature.targetMatching.enabled" : false,

3. Save your changes and restart the platform.

Enable uploading profile pictures

Optionally, you can configure the platform to all users to upload images to be used as their profile pictures. See User Profile Page.

Steps:

1. You can apply this change through the Admin Settings Page (recommended) or trifacta-conf.json. For more information, see Platform Configuration Methods.

2. Set the following parameter to true:

   "webapp.enableProfilePicture" : true,

3. Save your changes and restart the platform.

Disable enforced type casting

For non-schematized outputs,  Designer Cloud Enterprise Edition enforces casting of all values to the annotated data type of the column by default. For example, if the output value is -3.4 and the data type for the output column is Integer, the platform enforces Integer type casting and writes a null value instead.

This behavior is governed by the following parameter: webapp.enableTypecastOutput

Steps:

1. You can apply this change through the Admin Settings Page (recommended) or trifacta-conf.json. For more information, see Platform Configuration Methods.

2. Set the following parameter accordingly:

   "webapp.enableTypecastOutput" : true,

3. Save your changes and restart the platform.

Disable flow sharing

The flow sharing feature enables a user to share a flow with another user for collaboration. In this manner, a single source of truth can be retained as multiple users collaborate to transform the flow's datasets into the desired output. See Overview of Sharing.

Flow sharing is enabled by default. To disable flow sharing, please complete the following steps.

Steps:

1. You can apply this change through the Admin Settings Page (recommended) or trifacta-conf.json. For more information, see Platform Configuration Methods.

2. Set the following parameter to false:

   "feature.flowSharing.enabled" : true,

3. Save your changes and restart the platform.

Disable column lineage recipe highlighting

By default, the Designer Cloud application can display lineage highlighting of applicable steps for a selected column. When enabled, you can select Show related steps from a column's drop-down menu, and all recipe steps that reference the column are highlighted in the recipe panel. 

Please complete the following steps to disable this feature.

Steps:

1. You can apply this change through the Admin Settings Page (recommended) or trifacta-conf.json. For more information, see Platform Configuration Methods.

2. Set the webapp.enableColumnLineageScriptHighlighting configuration flag to false:

   "webapp.enableColumnLineageScriptHighlighting": false,

3. Save your changes and restart the platform.

Disable custom types

By default, you can create custom data types in Designer Cloud Enterprise Edition based off of a regular expression or an uploaded custom dictionaries of values. When a column is set to a custom data type, the values in the column are validated against the type specification. 

• For more information on creating custom data types using dictionary files, see Create Custom Data Types.

• For more information on creating custom data types using regular expression, see Create Custom Data Types Using RegEx.

  NOTE: Use of regular expressions is considered a developer-level skill.

To disable this feature, please complete the following steps.

Steps:

1. You can apply this change through the Admin Settings Page (recommended) or trifacta-conf.json. For more information, see Platform Configuration Methods.

2. Set the following to false:

   "feature.enableCustomTypes": false,

3. Save changes and restart the platform.
