Release 6.4

August 1, 2019

This release of  Trifacta® Wrangler Enterprise features broad improvements to the recipe development experience, including multi-step operations and improved copied and paste within the Recipe panel. As a result of the panel's redesign, you can now create user-defined macros, which are sets of sequenced and parameterized steps for easy reuse and adaptation for other recipes. When jobs are executed, detailed monitoring provides enhanced information on progress of the job through each phase of the process. You can also connect to a broader ecosystem of sources and targets, including enhancements to the integration with Tableau Server and AWS Glue. New for this release: read from your Snowflake sources. Read on for additional details on new features and enhancements.

What's New

Transformer Page:

  • The redesigned Recipe panel enables multi-step operations and more robust copy and paste actions. See Recipe Panel.
  • Introducing user-defined macros, which enable saving and reusing sequences of steps. For more information, see Overview of Macros.
  • Transform by example output values for a column of values. See Transformation by Example Page.
  • Browse current flow for datasets or recipes to join into the current recipe. See Join Window.
  • Replace specific cell values. See Replace Cell Values.

Job Execution:

Install:

Connectivity:

  • Support for Snowflake database connections.

    NOTE: This feature is supported only when Trifacta Wrangler Enterprise is installed on customer-managed AWS infrastructure.

    For more information, see Enable Snowflake Connections.

Enhanced support for AWS Glue integration:

Import:

  • Add timestamp parameters to your custom SQL statements to enable data import relative to the job execution time. See Create Dataset with SQL.

Authentication:

  • Leverage your enterprise's SAML identity provider to pass through a set of IAM roles that Trifacta users can select for access to AWS resources.

    NOTE: This authentication method is supported only if SSO authentication has been enabled using the platform-native SAML authentication method. For more information, see Configure SSO for SAML.

    For more information, see Configure for AWS SAML Passthrough Authentication.


Admin:

  • Administrators can review, enable, disable, and delete schedules through the application. See Schedules Page.

Sharing:

  • Share flows and connections with groups of users imported from your LDAP identity provider.
    NOTE: This feature is in Beta release.

    See Configure Users and Groups.

Logging:

Language:

  • New functions. See Changes to the Language.
  • Broader support for metadata references. For Excel files, $filepath references now return the location of the source Excel file. Sheet names are appended to the end of the reference. See Source Metadata References.

APIs:

Databases:

  • New databases:

    • Job Metadata Service database

Changes in System Behavior

NOTE: The Trifacta software must now be installed on an edge node of the cluster. Existing customers who cannot migrate to an edge node will be supported. You will be required to update cluster files on the Trifacta node whenever they change, and cluster upgrades may be more complicated. You should migrate your installation to an edge node if possible. For more information, see System Requirements.

NOTE: The v3 APIs are no longer supported. Please migrate immediately to using the v4 APIs.

NOTE: The command line interface (CLI) is no longer available. Please migrate immediately to using the v4 APIs.


NOTE: The PNaCl browser client extension is no longer supported. Please verify that all users of Trifacta Wrangler Enterprise are using a supported version of Google Chrome, which automatically enables use of WebAssembly. For more information, see Desktop Requirements.

NOTE: Support for Java 7 has been deprecated in the platform. Please upgrade to Java 8 on the Trifacta node and any connected cluster. Some versions of Cloudera may install Java 7 by default.


NOTE: The Chat with us feature is no longer available. For Trifacta Wrangler Enterprise customers, this feature had to be enabled in the product. For more information, see Trifacta Support.


NOTE: The desktop version of Trifacta Wrangler will cease operations on August 31, 2019. If you are still using the product at that time, your data will be lost. Please transition to using the free Cloud version of Trifacta® Wrangler. Automated migration is not available. To register for a free account, please visit https://cloud.trifacta.com.


Workspace:

API:

  • The endpoint used to assign an AWSConfig object to a user has been replaced. 

    NOTE: If you used the APIs to assign AWSConfig objects in a previous release, you must update your scripts to assign AWS configurations. For more information, see Changes to the APIs.

Documentation:

  • In prior releases, the documentation listed UTF32-BE and UTF32-LE as supported file formats. These formats are not supported. Documentation has been updated to correct this error. See Supported File Encoding Types
