def terminate_workflow_execution(domain=None, workflowId=None, runId=None,
    reason=None, details=None, childPolicy=None):
    """
    Records a WorkflowExecutionTerminated event and forces closure of the workflow execution identified by the given domain, runId, and workflowId. The child policy, registered with the workflow type or specified when starting this execution, is applied to any open child workflow executions of this workflow execution.
    Access Control
    You can use IAM policies to control this action's access to Amazon SWF resources as follows:
    If the caller does not have sufficient permissions to invoke the action, or the parameter values fall outside the specified constraints, the action fails. The associated event attribute's cause parameter will be set to OPERATION_NOT_PERMITTED. For details and example IAM policies, see Using IAM to Manage Access to Amazon SWF Workflows .

    :type domain: string
    :param domain: [REQUIRED]
            The domain of the workflow execution to terminate.
            

    :type workflowId: string
    :param workflowId: [REQUIRED]
            The workflowId of the workflow execution to terminate.
            

    :type runId: string
    :param runId: The runId of the workflow execution to terminate.

    :type reason: string
    :param reason: Optional. A descriptive reason for terminating the workflow execution.

    :type details: string
    :param details: Optional. Details for terminating the workflow execution.

    :type childPolicy: string
    :param childPolicy: If set, specifies the policy to use for the child workflow executions of the workflow execution being terminated. This policy overrides the child policy specified for the workflow execution at registration time or when starting the execution.
            The supported child policies are:
            TERMINATE: the child executions will be terminated.
            REQUEST_CANCEL: a request to cancel will be attempted for each child execution by recording a WorkflowExecutionCancelRequested event in its history. It is up to the decider to take appropriate actions when it receives an execution history with this event.
            ABANDON: no action will be taken. The child executions will continue to run.
            Note
            A child policy for this workflow execution must be specified either as a default for the workflow type or through this parameter. If neither this parameter is set nor a default child policy was specified at registration time then a fault will be returned.
            

    :returns: 
    domain (string) -- [REQUIRED]
    The domain of the workflow execution to terminate.
    
    workflowId (string) -- [REQUIRED]
    The workflowId of the workflow execution to terminate.
    
    runId (string) -- The runId of the workflow execution to terminate.
    reason (string) -- Optional. A descriptive reason for terminating the workflow execution.
    details (string) -- Optional. Details for terminating the workflow execution.
    childPolicy (string) -- If set, specifies the policy to use for the child workflow executions of the workflow execution being terminated. This policy overrides the child policy specified for the workflow execution at registration time or when starting the execution.
    The supported child policies are:

    REQUEST_CANCEL: a request to cancel will be attempted for each child execution by recording a WorkflowExecutionCancelRequested event in its history. It is up to the decider to take appropriate actions when it receives an execution history with this event.
    ABANDON: no action will be taken. The child executions will continue to run.
