Specify column headers during import:

You can specify the column headers for your dataset during import. For more information, see Import Data Page.

Sample Jobs Page:

You can monitor the status of all sample jobs that you have generated. Project administrators can access all sample jobs in the workspace. For more information, see Sample Jobs Page.

Job results:

Results of data quality checks are now part of the visual profile PDF available with your job results. In the PDF, you can download the data quality results over the entire dataset.

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

  • Visual profiling must be enabled for the job.
  • For more information, see Job Details Page.

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.

API:

  • You can now transfer ownership of assets created in Cloud Dataprep by TRIFACTA INC. between users, based on their user identifiers or email addresses. For more information, see Changes to the APIs.
  • Customize connection types (connectors) to ensure consistency across all connections of the same type and to meet your enterprise requirements. For more information, see Changes to the APIs.

Macro updates:

You can replace an existing macro definition with a macro that you have exported to your local desktop.

NOTE: Before you replace the existing macro, you must export a macro to your local desktop. For more information, see Export Macro.

For more information, see Macros Page.

Changes

Freed IP address ranges:

The following IP address range is the only one in use by the Trifacta Service:

34.68.114.64/28

Please discontinue whitelisting any other IP address ranges for the Trifacta Service.

These ranges have been freed to the general Internet.

Changes to Preferences:

The Preferences area of the Trifacta application has been changed. For more information, see Changes to Configuration.

Deprecated

None.

Known Issues

  • TD-58523: Cannot import dataset with filename in Korean alphabet from HDFS.

    • Workaround: You can upload files with Korean characters from your desktop. You can also add a 1 to the end of the file on HDFS, and it can then be imported.

  • TD-55299: Imported datasets with encodings other than UTF-8 and line delimiters other than \n may generate empty outputs on Spark or Cloud Dataflow running environments.

  • TD-51516: Input data containing BOM (byte order mark) characters may cause Spark or Cloud Dataflow running environments to read data improperly and/or generate invalid results.

Fixes

  • TD-56170: The Test Connection button for some relational connection types does not perform a test authentication of user credentials.
  • TD-54440: Header sizes at intermediate nodes for JDBC queries cannot be larger than 16K.
    • Previously, the column names for JDBC data sources were passed as part of a header in a GET request. For very wide datasets, these GET requests often exceeded 16K in size, which represented a security risk

Release 8.0

Features

Tip: Add a profile picture to your account! For more information, see User Profile Page.

Flow templates:

Introducing flow templates, which are predefined flows with guidelines for creating the flow objects needed to solve a specific transformation and publication use case. These step-by-step guides leverage placeholders for flow objects to assist you in rapidly assembling your end-to-end flow pipeline.

The first available template simplifies the Data Warehouse Onboarding process, which simplifies the ingestion of datasets, transformation of them, and loading them into your data warehouse. From the Home page, you can quickly set up a pipeline from data lakes into data warehouses:

  • GCS to BigQuery pipeline: Use this template to create a flow by importing a Google Cloud Storage, transforming the data, and publishing the outputs on the BigQuery. For more information, see Start with a Template.

Authorization:

APIs:

  • Individual workspace users can be permitted to create and use their own access tokens for use with the REST APIs. For more information, see Dataprep Project Settings Page.

Connectivity:

Import:

  • Improved method for conversion and ingestion of XLS/XSLX files. For more information, see Import Excel Data.

Recipe development:

  • The Flag for Review feature enables you to set review checkpoints in your recipes. You can flag recipe steps for review by other collaborators for review and approval. For more information, see Flag for Review.

Metric-based data quality rules:

Update Macros:

  • Replace / overwrite an existing macro's steps and inputs with a newly created macro.
  • Map new macro parameters to the existing parameters before replacing.
  • Edit macro input names and default values as needed. 

Job execution:

  • You can enable the Trifacta application to apply SQL filter pushdowns to your relational datasources to remove unused rows before their data is imported for a job execution. This optimization can significantly improve performance as less data is transferred during the job run. For more information, see Flow Optimization Settings Dialog.
  • Optimizations that were applied during the job run now appear in the Job Details Page. See Job Details Page.

Changes

None.

Deprecated

None.

Known Issues

  • TD-56830: Receive malformed_query: enter a filter criterion when importing table from Salesforce.

    • Feature Availability: This feature is available in Cloud Dataprep Premium by TRIFACTA INC. only.
    • NOTE: Some Salesforce tables require mandatory filters when they are queried. Mandatory filters are not currently supported for Salesforce connections


  • TD-56170: The Test Connection button for some relational connection types does not perform a test authentication of user credentials.

    • Workaround: Append the following to your Connect String Options:

      ;ConnectOnOpen=true
    • This option forces the connection to validate user credentials as part of the connection. There may be a performance penalty when this option is used.

Fixes

None.

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.
