NOTE: If the job is executed in an environment other than Trifacta Photon, the job is queued for execution in the environment. Jobs executed on a remote cluster may incur additional overhead to spin up execution nodes, which is typically within 10-15 seconds. During job execution, the Dataprep by Trifacta Cloudobserves the job in progress and reports progress as needed back into the application. The Dataprep by Trifacta Cloud does not control the execution of the job.
Cancel job: Click this button to cancel your job while it is still in progress. This button may not appear until the queued job has been submitted to the running environment.
NOTE: This option may not be available for all running environments. Job cancellation is not supported in high-availability deployments.
NOTE: If you do not have permission to cancel a Dataflow job, the appropriate permissions must be added to your IAM role by an administrator. The default IAM role available with the product has these permissions, but these permissions may not be present if you are using a custom or personal IAM role in your account. For more information on IAM permissions, see Required Dataprep User Permissions.
NOTE: In some cases, the product is unable to cancel the job from the application. In these cases, click View in Dataflow, and from there you can cancel the job in progress.
View dataflow job: View the job that was executed on Dataflow.
View BigQuery job: If the job was able to be executed in BigQuery, you can review the job in the BigQuery console.
NOTE: When you view the job in BigQuery, you are using your own credentials to access the BigQuery console, which may be different from the service account that was used to execute the job. In this case, the job in BigQuery may be reported having errors when viewed using your credentials, when the job succeeded using the service account. To see the job properly, the
bigquery.jobs.listpermissions must be added to your account. For more information, see Required Dataprep User Permissions.
- Jobs can be executed in BigQuery if all data sources and outputs are located in BigQuery. Additional requirements apply. For more information, see Overview of Job Execution.

This panel provides information on the progress and completion status of each stage of the job execution.
Tip: Depending on the operation, you may be able to monitor transfer rate performance for larger datasets.
- Connect: The platform is attempting to connect to the datastore hosting the asset sources for the datasets.
- Schema validation: When enabled, the schemas of a job's datasources are checked as the first step of job execution.
- Datasets with changes in them are reported at the top of the list. Click View all to see schema validation for all of the datasets used in the job in the Data sources tab.
- Optionally, the job can be halted if there are differences between the schema that is read and the schema that has been stored from the previous job run. This option can prevent data corruption.
- If no errors are detected, then the job is completed as normal.
- For more information on schema validation, see Overview of Schema Management.
- Request: The platform is requesting the set of assets to deliver.
- Ingest: Depending on the type of source data, some jobs ingest data to the base storage layer in a converted format before processing begins. This ingested data is purged after job completion.
- Prepare: (Publishing only) Depending on the destination, the Prepare phase includes the creation of temporary tables, generation of manifest files, and the fetching of extra connections for parallel data transfer.
- Transfer: Assets are transferred to the target, which can be the platform or to the output datastore.
Transform: This stage covers the execution of transformations on the source data.
Profile: If you chose to profile your output data, this stage is completed after transformation is complete. Results are available in the Profile tab.
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.
Publish: This stage covers the writing of the outputs of the transformed data. These outputs are available through the Output destinations tab.
- Process: Cleanup after data transfer, including the dropping of temporary tables or copying data within the instance.
For more information, see Overview of Job Monitoring.
If present, you can click the Show Warnings link to see any warnings pertaining to recipe errors, including the relevant step number.

- If you chose to profile results of your job, click View profile to review. See Profile tab below.
- A visual profile provides a graphical snapshot of the results of a successful transformation job for the entire dataset and individual columns in the dataset.
- If your job output specified SQL scripts to run before or after job execution, you can track their progress in the following stages:
- Pre-ingest SQL: Script that is configured to run before the source data is ingested to the platform.
- Post-publish SQL: Script that is configure to run after the output data has been published.
- For additional details, see the SQL scripts tab below.
- For more information on SQL scripts in job execution, see Create Output SQL Scripts.
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.

For jobs sourced from relational datasets, you can optionally enable SQL-based optimizations, which apply some of the steps specified in your recipe back in the datasource, where they can be executed before the data is transferred to the running environment for execution. Using these optimizations means faster performance based on a lower volume of data transfer.Project owners must enable the optimization feature for the project. For more information, see Dataprep Project Settings Page.
Optimizations must be enabled. You can also select the optimizations to apply.
When optimizations have been applied, they are listed on the Overview tab:
Optimization: This setting is displayed if optimizations have been enabled.
Columns pruned: If one or more unused columns have been pruned in the datasource via SQL, the count of columns is listed here.
Filters pushed down: If one or more row filters has been applied in the datasource via SQL, the count of filters is listed here.
If an optimization is disabled or was not applied to the job run, it is not listed.
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:

Create imported dataset
Optionally, you can turn your generated results into new datasets for immediate use in the Dataprep by Trifacta Cloud. 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.
If the Dataprep by Trifacta Cloud 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.
SQL scripts Tab
If the output for your job included one or more pre- or post-job SQL script executions, you can review the status of their execution during the job.
NOTE: If a SQL script fails to execute, all downstream phases of the job fail to execute.
Tip: If the SQL script execution for this job encountered errors, you can review those errors through this tab. For more detailed information, click Download logs.
Connection: Name of the connection through which the script was executed.
SQL statement: The first part of the SQL script that was executed.
Run before data ingest- script was executed pre-job.
Run after data publish- script was executed post-job, after the job results had been written.
Status: Current status and execution duration of the SQL script.
NOTE: If you have multiple SQL scripts for each settings, they may execute in parallel. For example, if you created three pre-job SQL scripts, there is no guarantee that they executed in the order in which they are listed.
Hover over a SQL script entry and click View details.
In the SQL script details window, you can review:
Connection and SQL of the executed script.
Any error messages that occurred during execution.
Tip: To review log information for any error messages, click Download logs.

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.
Download as PDF: Download your visual profile and results of your data quality rules on the entire dataset 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.
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).
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.
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.
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.
