Features


Introducing Cloud Dataprep Premium by TRIFACTA INC. and Cloud Dataprep Standard by TRIFACTA INC.: You can now upgrade your existing Cloud Dataprep by TRIFACTA INC. projects to unlock advanced features, such as broader API access and relational connectivity. To see the full set of new capabilities and use cases, see https://www.trifacta.com/products/pricing/cloud-dataprep/.

 

Relational connectivity: Connect to relational sources to import data and, where supported, write results. 

 


Advanced Cloud Dataflow execution options: Specify additional job execution options at the project level or for individual jobs. 

  • Feature Availability: This feature is available in Cloud Dataprep Premium by TRIFACTA® INC.
  • Assign scaling algorithms for managing Google Compute Engine instances or define minimum and maximum workers to use.
  • Specify the service account and any billing labels to apply to your jobs.

Introducing plans: A plan is a sequence of tasks on one or more flows that can be scheduled.

  • Feature Availability: This feature is available in Cloud Dataprep Premium by TRIFACTA INC.
  • NOTE: In this release, the only type of task that is supported is Run Flow.
  • For more information on plans, see Plans Page.

Dataflow execution in non-local VPC: You can now execute your Cloud Dataflow jobs on a non-local or shared virtual private network (VPC).

  • NOTE: To accommodate a wider range of shared VPCs configuration, subnetworks must be specified by full URL. See Changes below.
  • Project owners can set these execution options for the entire project. See Project Settings Page.

 

Changes

Subnetwork specified by URL: When you are specifying the subnetwork where to execute your Cloud Dataflow jobs, you must now specify the subnetwork using a URL.

  • Tip: This feature can be used when Cloud Dataprep by TRIFACTA INC. is configured to execute Cloud Dataflow jobs to run within a shared VPC hosted in a project other than the current project.
  • Previously, you could specify the subnetwork by name. However, non-local subnetwork values could not be specified in this manner.
  • For more information, see Dataflow Execution Settings.

 

Deprecated

None.

Known Issues

Soft validation errors during job execution for imported flow: If you import a flow from Cloud Dataprep Premium by TRIFACTA INC. into Cloud Dataprep Standard by TRIFACTA INC., you may encounter soft validation errors during job execution. 

  • If the imported flow uses custom VPC mode, then the job execution may fail, since network may be inaccessible.
  • Workaround: 1) set the VPC mode to Auto or 2) set accessible VPC options before you run your job. See Dataflow Execution Settings.

 

Fixes

None.
