BPMN is widely used for human-centric workflows, where human intervention is required at various stages of a process. Within Apache KIE, the User Task Subsystem is designed to manage User Task nodes, ensuring seamless execution and API-driven interaction.

​
How User Task Nodes Work

  • User Task nodes define tasks requiring human action, including assignees, deadlines, and escalation rules.
  • When a User Task node is triggered, it interacts with the User Task Subsystem, which manages task lifecycles and execution contexts.

​
Dedicated API and Lifecycle Management

Apache KIE prioritizes developer-centric automation, and the User Task Subsystem provides a dedicated API to facilitate task management. This API enables:
  • Task assignment & delegation
  • Task state transitions (e.g., start, complete, suspend, resume)
  • Deadline management and notifications

​
Upcoming Changes in Apache KIE 10.1.0

  • Task Console (Deprecated in 10.0.0): Previously provided a UI for task management but will be removed in future releases.
  • New Subsystem in 10.1.0: Enhances the current architecture to improve scalability and feature support.
By leveraging the User Task Subsystem, developers can seamlessly integrate human tasks into their workflow automation, ensuring greater flexibility and control over task execution.
