What's New

Import:

• The maximum permitted size of a file uploaded through Trifacta application has been increased from 100 MB to 1 GB.

Plan View:

• Import and Export Plans: You can import and export plans from one environment, workspace, or projects to others.

For more information, see Export Plan.

For more information, see Import Plan.

• Share Plans: Share plans with one or more users to work together on the same plan. For more information, see Share a Plan.
• Email notifications: Send email notifications to plan owners and collaborators based on the status of execution of plans. For more information, see Manage Plan Notifications Dialog.

Photon:

Introducing Trifacta Photon, an in-memory running environment for running jobs. Embedded in the Trifacta Wrangler Pro, Trifacta Photon is fast and best-suited for small- to medium-sized jobs.

• When you choose to run a job, you can now choose to run a job on Trifacta Photon.
• Trifacta Wrangler Pro specifies the most appropriate running environment as the default selection based on the size of your job.
• For more information, see Run Job Page.

Sampling:

• Trifacta Photon also enables quick scan sampling. A quick scan sample generates an appropriate selection of rows from the dataset from which to perform the sample. These samples are faster to generate. For more information, see Overview of Sampling.
• For more information on generating samples, see Samples Panel.

Sharing:

• Define permissions on individual objects when they are shared.
  
  

  NOTE: Fine-grained sharing permissions apply to flows and connections only.

  For more information, see Changes to User Management.

• Support for using OAuth2 for Snowflake connections. For more information, see OAuth2 for Snowflake.

Connectivity:

• Improved Salesforce connection type.
  
  

  For more information, see Create Salesforce Connections.

API:

• Experimental feature: Export Python Pandas code to generate the transformation steps required to produce a defined output object.
  

• NOTE: This feature can be changed or removed from the platform at any time without notice. Do not deploy it in a production environment.
  
• For more information, see API Workflow - Wrangle Output to Python.

Changes in System Behavior

New public bucket for product assets

In prior releases, the product referenced the following S3 bucket, which contained demo assets:

Release 7.9

What's New

Plan View:

• Execute Plan using status rules: Starting in Release 7.9, you can execute tasks based on the previous task execution result. For more information, see Create a Plan.
• Execute Parallel Plan tasks: In previous releases, plans were limited to a sequential order of task execution. Beginning in Release 7.9, you can create branches in the graph into separate parallel nodes, enabling the corresponding tasks to run in parallel. This feature enables you to have a greater level of control of your plans' workflows. For more information, see Create a Plan.
• Zoom options: Zoom control options and keyboard shortcuts have been introduced in the plan canvas. For more information, see Plan View Page.
• Filter Plan Runs: Filter your plan runs based on dates or plan types. For more information, see Plan Runs Page. 

Transform Builder:

• An All option has been added for selecting columns in the Transform Builder.  For more information, see Changes to the Language.

Changes in System Behavior

Flow optimizations re-enabled:

For  Trifacta Wrangler Pro, flow execution optimizations were disabled in an earlier release due to to technical issues. These optimizations are designed to improve query performance during job and sampling execution. 

Beginning in this release, flow optimizations are re-enabled for new flows. When you create a new flow now, flow optimizations are automatically enabled for it.

• By default, flow optimizations are enabled for the entire workspace. They can be disabled if necessary. See Workspace Settings Page.

• For flows created in a previous release, flow optimizations are disabled by default. You can choose to enable optimizations for an individual flow through Flow View page.

  NOTE: If a flow execution fails multiple consecutive times, flow optimizations are automatically skipped. If job execution then succeeds, optimizations are automatically disabled for the flow.

  For more information, see Manage Flow Advanced Settings Dialog.

Better license management:

In prior releases, the Trifacta application locked out all users if the number of active users exceeded the number permitted by the license. This situation could occur if users were being added via API, for example. 

Beginning in this release, the Trifacta application does not block access when the number of licensed users is exceeded.

Release 7.7

What's New

None.

Changes in System Behavior

Disabled Optimizer Service

In the September release, the Optimizer service was introduced, which enabled users to apply advanced physical and logical optimizations for flow and job executions. Recently, an issue was discovered, which has caused us to disable the service temporarily.

• This issue affected a very small number of users who were using the new feature. Now that the feature is disabled, impacted users should experience impacts only to performance of flow and job executions. Performance should be similar to pre-release of the service.
• The Optimizer service was disabled through a configuration change that did not require any service interruptions. Users should not experience any loss of functionality or availability due to the work to resolve this issue.
• The Trifacta Engineering team is actively working to resolve the issue. Thank you for patience. If you have further questions, please contact  Trifacta Support.

  See Flow View Page.

Import:

• For long-loading relational datasets, you can monitor the ingest process through Flow View as you continue your work.

  For more information, see Flow View Page.

• Improved performance when browsing databases for tables to import.

Enhanced PII masking:

• For social security numbers and credit card numbers, the methods by which these values are determined for purposes of masking sensitive Personally Identifiable Information (PII) has been expanded and improved. For more information, see Improvements to the Type System.
