Set Up a Pipeline

To set up a Tetra Data Pipeline, you must do the following:

• Step 1: Define Trigger Conditions
• Step 2: Select the Protocol
• Step 3: Set Notifications
• Step 4: Finalize the Details and Settings

Step 1: Define Trigger Conditions

🚧

IMPORTANT

You can’t use a new attribute as a pipeline trigger until you add a file to the TDP that includes the attribute. For instructions on how to manually upload files, see Upload a New File or New Version of the File.

Trigger conditions indicate the criteria a file must meet for pipeline processing to begin. There are two types of trigger conditions:

• Simple trigger conditions require files to meet just one condition to trigger the pipeline. For example, you can configure data files that have a specific label to trigger a pipeline.
• Complex trigger conditions require files to meet several conditions before they trigger the pipeline. For example, you can require a file to have both a specific label and file path to trigger a pipeline. Complex trigger conditions can be combined by using standard Boolean operators (AND/OR) and can be nested.

To define your pipeline's trigger conditions, do the following:

1. Open the Pipeline Manager page. Then, select the upper right New Pipeline button. The New Pipeline page appears.
2. In the Define Trigger section, select a trigger type from the File Category drop-down list. For more information about each trigger type, see the following Trigger Types table.

📘

NOTE

Trigger types are divided into two categories: Platform Metadata and Custom Metadata. Platform Metadata types are available to all TDP users. Custom Metadata types are available to your organization only.

Trigger Types

3. In the middle drop-down list, enter how you want the trigger to match the value you'll set for the trigger condition by selecting the relevant conditional operator (is or is not).
4. In the Value field, enter the value for the trigger condition that you want or select an option from the drop-down list.

📘

NOTE

Using Pipeline is not verifies that there is a pipeline value and that it's not the value that is specified. This is FALSE for files that have not been processed through a pipeline.

5. (Optional) To add another condition to your trigger, choose Add Field. Then, repeat steps 2-4. To configure the pipeline to run if the file meets both trigger conditions, select Matches All-AND from the top drop-down list. To configure the pipeline to run if the file meets at least one trigger condition, select Matches All-ANY from the top drop-down list.
6. (Optional) To nest trigger conditions, choose Add Field Group. Then, repeat steps 2-6.
7. Choose Next.

Step 2: Select and Configure the Protocol

After you've defined a trigger, select and configure the protocol. For more information about protocols and how they work with pipelines, see Tetra Data Pipeline Overview and Available Tetra Data Models.

To select and configure a protocol, do the following:

1. In the Select Protocol section of the Pipeline Manager page, select a protocol from the list on the left. You can also search for a specific protocol by entering text in the upper left search field.
2. In the Configuration section, enter the configuration options for the protocol, if there are any.
3. (Optional) To see more information about the protocol the script, select the View Details button. A page that contains the protocol's protocol.json and script.js files appears. The protocol.json file defines the protocol. It provides a brief description of the steps run and the configurations. The script.js file shows the workflow.
4. (Optional) To see more information about the protocol steps, choose README in the Steps section.
5. (Optional) To configure custom memory settings for each step of the pipeline, select a memory option from from the Default Memory drop-down list in the Steps section. For more information, see the Memory and Compute Settings section of this procedure.
6. Choose Select this Protocol.
7. Choose Next.

Step 3: Set Notifications

To configure email notifications about successful and failed pipeline executions, do the following:

1. In the Set Notifications section of the Pipeline Manager page, select one of the following toggles based on the type of notifications that you want to send:
   • Send on successful pipelines—sends an email after the pipeline runs successfully.
     -or-
   • Send on failed pipelines—sends an email after the pipeline fails.
2. In the Add an e-mail address field, enter the email address that you want to send the notifications to. To add more than one address, select the Add an email address field that appears below the one you just entered and enter another email address.
3. Choose Next.

📘

NOTE:

For maintenance purposes, make sure that you use a group alias for notification email addresses instead of individuals' emails.

Step 4: Finalize the Details

To configure the remaining details you need to finish creating your pipeline, enter the following information into the Finalize Details section of the Pipeline Manager page:

1. For PIPELINE NAME, enter a name for the pipeline.
2. For PIPELINE DESCRIPTION, enter a description of the pipeline.
3. Do one of the following:
   • If you want the pipeline to be available for processing files, move the ENABLED toggle to the right. It appears blue when the pipeline is active.
     -or-
   • If you don't want the pipeline to be available for processing files yet, move the ENABLED toggle to the left. It appears gray when the pipeline is inactive.
4. For MAX PARALLEL WORKFLOWS, it's typically a best practice to not change the default value (0). The default 0 value indicates that the pipeline allows an unlimited number of concurrent workflows, which helps with throughput. If one of the following situations applies, contact your customer success manager (CSM) to determine the correct MAX PARALLEL WORKFLOWS setting for your use case:
   • For pipelines that must process one file at a time only, with zero parallel processing, MAX PARALLEL WORKFLOWS can be set to 1.
   • For uploading or processing a high number of files at the same time when there are upstream systems that can't handle the required rate of parallel processing, MAX PARALLEL WORKFLOWS can be set to a low number.
   • For processing a high number of files with a long-running pipeline processess, MAX PARALLEL WORKFLOWS can be set to a low number.

     🚧

     IMPORTANT

     Changing the MAX PARALLEL WORKFLOWS setting from the default 0 value severely limits pipeline throughput and must be done in collaboration with your CSM.

5. For PRIORITY, select the pipeline's priority level. Increasing or decreasing this value will adjust the slot assignment prioritization for that pipeline within the organization, which raises or lowers the likelihood that the pipeline's workflows are scheduled before another pipeline's. You can assign a priority number from 1-10, where 10 is the highest priority and 1 is the lowest. For example, a pipeline with a priority of 1 is less likely to have a workflow scheduled before a pipeline with a priority of 10. The default setting is 5. This setting is typically used to decrease the likelihood a pipeline is run before others to prevent it from constraining resources.
6. (Optional) To override the pipeline's default retry behavior setting, select another option from the RETRY BEHAVIOR drop-down list. The default rety setting for pipelines that use the protocol.yml protocol definition file format is Exponential retry interval increasing (default). The default retry setting for all other pipelines is Always retry 3 times. For more information, see Retry Behavior Settings.
7. Choose Create.

📘

NOTE

If the ENABLED toggle is set to active when you choose Create, then the pipeline will run as soon as the configured trigger conditions are met.

Retry Behavior Settings

If a pipeline fails for any reason, the TDP automatically retries running the pipeline again up to three times before the pipeline fails. You can change this default retry behavior when you create or edit a pipeline on the Pipeline Management page by selecting one of the following retry settings.

You can also manually retry a failed pipeline by selecting the Retry button that displays next to the pipeline's workflow steps in the TDP.

📘

NOTE

Each pipeline retry uses double the memory of the previous attempt to run the pipeline, up to 120 GB. Compute and CPU capacity will also increase based on the amount of memory used for each retry. This increase in memory and compute usage can increase the cost of processing files significantly. For more information, see the Memory and Compute Settings section of this procedure.

Preconfigured Pipeline Retry Settings

Custom Pipeline Retry Settings

📘

NOTE

Custom pipeline retry behavior settings are available for pipelines that use the protocol.yml protocol definition file format only. For more information, see Protocol YAML Files.

Memory and Compute Settings

When configuring a protocol, you can override the default memory setting with a custom memory setting for each step of a pipeline. To configure a custom memory setting for a pipeline step, select the Default Memory drop-down list in the Step section of the Pipeline Manager page.

The following table shows the available memory setting options and how much compute capacity each setting uses:
