In Dataprep by Trifacta®, you use the Job Details page to explore details about successful or failed jobs, including outputs, dependencies, and other metadata. Download results to your local desktop or, if enabled, explore a visual profile of the data in the results for further iteration on your recipe.
View dataflow job: View the job that was executed on Dataflow.
- Download profile as PDF: If visual profiling was enabled for the job, you can download the profile in PDF format.
Download profile as JSON: If visual profiling was enabled for the job, you can download a JSON representation of the profile to your desktop.
Tip: When you download your JSON profile, any rules applied to the generated results are included in the profile. Search for
In the Overview tab, you can review the job status, its sources, and the details of the job run.
NOTE: If your job failed, you may be prompted with an error message indicating a job ID that differs from the listed one. This job ID refers to the sub-job that is part of the job listed in the Job summary.
You can review a snapshot of the results of your job.
NOTE: If you chose to generate a profile of your job results, the transformation and profiling tasks may be combined into a single task, depending on your environment. If they are combined and profiling fails, any publishing tasks defined in the job are not launched. You may be able to ad-hoc publish the generated results. See below.
- To review the recipe and dependencies in your job, click View steps and dependencies. See the Dependencies tab below.
- If you chose to profile results of your job, click View profile to review. See Profile tab below.
- To view the job that was executed, click View dataflow job.
You can also review the outputs generated as a result of your job. To review and export any of the generated results, click View all. See Outputs Destinations tab below.

NOTE: You can re-run a failed job from the Transformer page. If you have since modified the recipe, those changes are applied during the second run. See Transformer Page.
- Flow: Name of the flow from which the job was executed. Click the link to open the flow. See Flow View Page.
- Output: Name of the output object that was used to define the generated results. Click the link to open the output. See Flow View Page.
- Job type: The method by which the job was executed:
Manual- Job was executed through the application interface.
Scheduled- Job was executed according to a predefined schedule. See Add Schedule Dialog.
- User: The user who launched the job
- Environment: Where applicable, the running environment where the job was executed is displayed.
- Start time: Timestamp for when processing began on the job. This value may not correspond to when the job was queued for execution.
- Finish time: Timestamp for when processing ended on the job, successful or not
- Last update: Timestamp for when the job was last updated
- Duration: Elapsed time of job execution
Output Destinations Tab
If the job has successfully completed, you can review the set of generated outputs and export results.
For each output, you can do the following:
View details: View details about the generated output in the side bar.
- View on Base Storage: View the results within the Base Storage. See Google Cloud Storage Browser.
Download result: Download the generated output to your local desktop.
NOTE: Some file formats may not be downloadable to your desktop. See below.
Create imported dataset: Use the generated output to create a new imported dataset for use in your flows. See below.
NOTE: This option is not available for all file formats.
Direct file download
Click one of the provided links to download the file through your browser to your local desktop.
NOTE: If these options are not available, data download may have been disabled by an administrator.
Create imported dataset
Optionally, you can turn your generated results into new datasets for immediate use in Dataprep by Trifacta. For the generated output, select Create imported dataset from its context menu.
NOTE: When you create a new dataset from your job results, the file or files that were written to the designated output location are used as the source. Depending on your backend datastore permissions are configured, this location may not be accessible to other users.
After the new output has been written, you can create new recipes from it. See Build Sequence of Datasets.
If Dataprep by Trifacta is connected to an external storage system, you may publish your job results to it. Requirements:
- Your version of the product supports publishing.
- Your connection to the storage system includes write permissions.
- Your results are generated in a format that the target system supports for writing.
- All sub-jobs, including profiling, successfully completed.
For more information, see Publishing Dialog.
Review the visual profile of your generated results in the Profile tab. Visual profiling can assist in identifying issues in your dataset that require further attention, including outlier values.
NOTE: This tab appears only if you selected to profile results in your job definition. See Run Job Page.
- Download as PDF: Download your visual profile as a PDF file.
- Download as JSON: Download your visual profile as a JSON file.
In particular, you should pay attention to the mismatched values and missing values counts, which identify the approximate percentage of affected values across the entire dataset. For more information, see Overview of Visual Profiling.
NOTE: The computational cost of generating exact visual profiling measurements on large datasets in interactive visual profiles severely impacts performance. As a result, visual profiles across an entire dataset represent statistically significant approximations.
NOTE: Dataprep by Trifacta treats null values as missing values. Imported values that are null are generated as missing values in job results (represented in the gray bar). See Manage Null Values.
Tip: Mouse over the color bars to see counts of values in the category.
Tip: Use the horizontal scroll bar to see profiles of all columns in wide datasets.
In the lower section, you can explore details of the transformations of individual columns. Use this area to explore mismatched or missing data elements in individual columns.
Depending on the data type of the column, varying information is displayed. For more information, see Column Statistics Reference.
Tip: You should review the type information for each column, which is indicated by the icon to the left of the column.
If you have defined data quality rules for your recipe, those rules are applied to the generated results. In the Rules tab, you can review the application of the rules across your entire dataset.
NOTE: To see the results of your rules on the entire dataset, you must enable profiling for the job. See Run Job Page.
- Results: Hover over the data quality bar to see the number of rows and percentage of rows that passed (green) or failed (red) the rule.
- Rule Description: The test applied to the values.
- Type: The type of rule. For more information, see Data Quality Rules Reference.
- Rule Updated At: Timestamp for when the rule was last modified.
Tip: When you download your profile as JSON, the rule definitions are included.
Data quality rules are created in the Transformer page. For more information, see Data Quality Rules Panel.
In this tab, you can review a simplified representation of the flow from which the job was executed. This flow view displays only the recipes and datasets that contributed to the generated results.
Tip: To open the full flow, you can click its name in the upper-left corner.
Download recipe: Download the text of the recipe in Wrangle .
Display Wrangle /natural language: Toggle display of the recipe in raw language or in readable language.
Data sources Tab
In the Data sources tab, you can review all of the sources of data for the executing recipe.
NOTE: If a flow is unshared with you, you cannot see or access the datasources for any jobs that you have already run on the flow, including any PDF profiles that you generated. You can still access the job results. This is a known issue.
If your flow references parameters, you can review the state of the parameters at the time of job execution.
NOTE: This tab appears only if the job is sourced from a flow that references parameters. For more information, see Overview of Parameterization.
When a webhook task has been triggered for this job, you can review the status of its delivery to the target system.
- Webhooks are defined on a per-flow basis. For more information, see Create Flow Webhook Task.
- Name: Display name for the webhook task.
- URL: Target URL where the webhook notification is delivered.
- Status: HTTP status code returned from the delivery of the message.
200- message was delivered successfully.
- Delivered: Timestamp for when the webhook was delivered.
