IDMC Data Integration Taskflows: Understanding Taskflows

Introduction

An essential aspect of Informatica Cloud Data Integration (ICDI) is managing and executing workflows known as taskflows. Taskflows control the execution sequence of Data Integration tasks based on the output of the previous task. They enable users to run tasks concurrently, employ sophisticated decision-making strategies, schedule tasks, and implement advanced orchestration features.

Taskflow Control

Taskflows serve as the foundation for managing and controlling the order in which Data Integration tasks are executed. They ensure that each task runs correctly by providing a structured framework that considers the dependencies between tasks. By defining the relationships between tasks, taskflows maintain the integrity and accuracy of the data being integrated.

Running Taskflows as APIs

One of the key advantages of ICDI taskflows is their ability to be published as APIs. This feature allows users to trigger taskflows from external applications and retrieve the status of the triggered events. To accomplish this, specific requirements must be met. Firstly, the allowed groups or users must be configured under the taskflow's start properties. Secondly, the taskflow must be published as a service to generate its corresponding service URL and SOAP service URL. When publishing a taskflow as an API, permissions must be adjusted, and the taskflow must be published as a service to make it accessible via API requests.

Running Taskflows from Various Sources

There are several methods to initiate a taskflow in ICDI. Some of the popular approaches include:

• From the Taskflow Designer: Users can manually click the 'Run' button present at the top-left of the page to execute the taskflow directly from the taskflow designer interface.
• As an API: To trigger a taskflow through an API, you need to first publish the taskflow as a service by navigating to Data Integration, selecting Explore, opening the desired taskflow, configuring the allowed groups or users appropriately, and then publishing the taskflow from the Actions menu on the top right corner of the page. Once published, users can invoke the taskflow from external applications via the generated endpoint URLs.
• Using RunAJob Utility: The RunAJob utility is a command-line tool used to initiate IICS Data Integration tasks. It internally calls the IICS REST API service and can be utilized to trigger taskflows.
• Through File Listeners: Taskflows can also be triggered through connector file listeners by defining the binding type as 'Event' and selecting the connector file listener as the event source within the taskflow. This mechanism allows the taskflow to subscribe to specified events, which in turn will initiate the workflow's execution.
• According to a Schedule: To run a taskflow based on a schedule, you need to create a schedule in Administrator and associate the taskflow with the set timeline. This ensures that the taskflow automatically runs at the predefined intervals without requiring manual intervention.

Conclusion

Taskflows play a crucial role in managing data integration processes using ICDI. They allow for efficient control of task execution sequences, provide advanced decision-making capabilities, enable parallel processing, and support recovery options. By publishing taskflows as APIs, users gain access to an extensive range of functionalities that facilitate seamless interaction with other applications and services, thereby enhancing overall operational efficiency and streamlining data pipeline management.
