Workflow and Task Status

The workflow and task statuses are crucial to understanding the execution mechanism in Conductor. You can check a workflow execution’s current status and task status from the Conductor UI or using API.

Workflow status

Once started, a workflow execution will either be in an ongoing or terminal status.

Status	Description
RUNNING	The workflow is in progress.
PAUSED	The workflow is paused by a user or external event, and is waiting for a manual action to resume.
COMPLETED	Terminal status where all the tasks in the workflow are completed.
TIMED_OUT	Terminal status where one of the workflow tasks has timed out.
TERMINATED	Terminal status where an incomplete workflow has been terminated by a user, event, or another workflow.
FAILED	Terminal status where the workflow has encountered an error and failed. You can retry the workflow execution from the failed task.

Task state transitions

During a workflow execution, each task will go through the state transitions illustrated in the figure below.

Task status

Each task will be in a scheduled, ongoing, or terminal status.

Status	Description
SCHEDULED	The task has been scheduled to be picked up by a worker.
IN_PROGRESS	The task is being executed by a worker.
SKIPPED	The task is skipped without executing, and the workflow continues to the subsequent tasks. Occurs if the Skip Task API is used during a currently running workflow.
TIMED_OUT	The task times out without being completed. Occurs if the task has been configured with the following timeout parameters in its task definition: timeOutPolicy. timeOutSeconds pollTimeoutSeconds responseTimeoutSeconds
CANCELED	The scheduled task has been canceled without being completed because the workflow has been terminated.
FAILED	The task failed to complete due to an error, and the workflow can be retried from the failed task.
FAILED_WITH_TERMINAL_ERROR	The task failed to complete due to an error and cannot be retried.
COMPLETED_WITH_ERRORS	The task has encountered some errors but is completed. Occurs only when a task is set as optional in the workflow definition and fails during execution. The workflow will continue even when there are errors.
COMPLETED	The task has been successfully completed without any errors.
