Release 7.8

Features

Plans:

  • Create HTTP tasks for your plans, which can be configured to issue a request to an API endpoint over HTTP.

    Feature Availability: This feature is available in Cloud Dataprep Premium by TRIFACTA INC.

 


Flow View:

  • Get started adding and building objects in your flows with new object placeholders.

  • Automatically organize the nodes of your flow with a single click.
  • The viewport position and zoom level are now preserved when returning to a given flow.

  • See Flows Page.

 


Data quality rules:

  • Improvements to suggestions for data quality rules:

    • Existing Data quality rules panel is updated with View suggestions button.
    • Data quality rules are now categorized by suggestions for individual columns.
    • Some rule types support the May be missing checkbox. When it is selected, the data quality rule allows missing values to be acceptable for a specified column. For more information on data quality rules, see Data Quality Rules Panel.

 


Language:

  • Rename columns now supports uppercase or lowercase characters or shorten column names to a specified character length from the left or right. For more information, see Rename Columns.

 


API: Modify the source Google Cloud Storage bucket and path for a defined imported dataset. Feature Availability: This feature is available in Cloud Dataprep Premium by TRIFACTA INC.

For more information, see API Workflow - Swap Datasets.

 

Changes

JDBC connection pooling disabled: The ability to create connection pools for JDBC-based connections has been disabled. It is likely to be removed in a future release. Feature Availability: This feature is available in Cloud Dataprep Premium by TRIFACTA INC.

 


Deprecated Parameter History Panel Feature: As a part of collaborative suggestions enhancement, the support for Parameter History panel is deprecated from the software. For more information on collaborative suggestions feature, see Overview of Predictive Transformation.

 

Automatic random samples are disabled: In prior releases, a random sample of the data was automatically generated for display when a recipe with source data greater than 10MB was first loaded into the Transformer page. The Initial Sample, which is the first set of rows in the dataset was displayed by default, and this automatic random sample was available for manually selection if needed.

NOTE: Recent issues with long-running random sample jobs require that the generation of automatic random samples must be disabled until the issues are addressed.

You can still generate random samples manually. If sample generation takes too long, you can cancel it and select a different sampling type. For more information, see Samples Panel.

 


Classic Flow View no longer available: In Release 7.6, an improved version of Flow View was released. At the time of release, users could switch back to using the classic version. 

Beginning in this release, the classic version of Flow View is no longer available. 

Tip: The objects in your flows that were created in classic Flow View may be misaligned in the new version of Flow View. You can use auto-arrange to re-align your flow objects.

For more information, see Flow View Page.

 


Enhanced Flow and Flow View menu options: The context menu options for Flow View and Flow have been renamed and reorganized for better user experience.

 


Salesforce connector disabled temporarily: In Release 7.8, the Salesforce connector has been disabled temporarily. In a future release, it will be replaced with an improved version of the Salesforce connector. Feature Availability: This feature is available in Cloud Dataprep Premium by TRIFACTA INC.

 

Key Bug Fixes

TD-53318: Cannot publish results to relational targets when flow name or output filename or table name contains a hyphen (e.g. my - filename.csv).

 

New Known Issues

TD-55503: When you swap datasets via API, existing samples are not discarded. These samples are invalid.

  • Workaround: This issue does not occur if you swap datasets through the Trifacta application. If it does occur via API, you can collect a new sample manually. See Samples Panel.

Release 7.6 push 3

Features

None.

Changes

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.
