Overview

Event within a workflow execution. A history event can be one of these types:

• ‘ActivityTaskCancelRequested` – A `RequestCancelActivityTask` decision was received by the system.

• ‘ActivityTaskCanceled` – The activity task was successfully canceled.

• ‘ActivityTaskCompleted` – An activity worker successfully completed an activity task by calling RespondActivityTaskCompleted.

• ‘ActivityTaskFailed` – An activity worker failed an activity task by calling RespondActivityTaskFailed.

• ‘ActivityTaskScheduled` – An activity task was scheduled for execution.

• ‘ActivityTaskStarted` – The scheduled activity task was dispatched to a worker.

• ‘ActivityTaskTimedOut` – The activity task timed out.

• ‘CancelTimerFailed` – Failed to process CancelTimer decision. This happens when the decision isn’t configured properly, for example no timer exists with the specified timer Id.

• ‘CancelWorkflowExecutionFailed` – A request to cancel a workflow execution failed.

• ‘ChildWorkflowExecutionCanceled` – A child workflow execution, started by this workflow execution, was canceled and closed.

• ‘ChildWorkflowExecutionCompleted` – A child workflow execution, started by this workflow execution, completed successfully and was closed.

• ‘ChildWorkflowExecutionFailed` – A child workflow execution, started by this workflow execution, failed to complete successfully and was closed.

• ‘ChildWorkflowExecutionStarted` – A child workflow execution was successfully started.

• ‘ChildWorkflowExecutionTerminated` – A child workflow execution, started by this workflow execution, was terminated.

• ‘ChildWorkflowExecutionTimedOut` – A child workflow execution, started by this workflow execution, timed out and was closed.

• ‘CompleteWorkflowExecutionFailed` – The workflow execution failed to complete.

• ‘ContinueAsNewWorkflowExecutionFailed` – The workflow execution failed to complete after being continued as a new workflow execution.

• ‘DecisionTaskCompleted` – The decider successfully completed a decision task by calling RespondDecisionTaskCompleted.

• ‘DecisionTaskScheduled` – A decision task was scheduled for the workflow execution.

• ‘DecisionTaskStarted` – The decision task was dispatched to a decider.

• ‘DecisionTaskTimedOut` – The decision task timed out.

• ‘ExternalWorkflowExecutionCancelRequested` – Request to cancel an external workflow execution was successfully delivered to the target execution.

• ‘ExternalWorkflowExecutionSignaled` – A signal, requested by this workflow execution, was successfully delivered to the target external workflow execution.

• ‘FailWorkflowExecutionFailed` – A request to mark a workflow execution as failed, itself failed.

• ‘MarkerRecorded` – A marker was recorded in the workflow history as the result of a `RecordMarker` decision.

• ‘RecordMarkerFailed` – A `RecordMarker` decision was returned as failed.

• ‘RequestCancelActivityTaskFailed` – Failed to process RequestCancelActivityTask decision. This happens when the decision isn’t configured properly.

• ‘RequestCancelExternalWorkflowExecutionFailed` – Request to cancel an external workflow execution failed.

• ‘RequestCancelExternalWorkflowExecutionInitiated` – A request was made to request the cancellation of an external workflow execution.

• ‘ScheduleActivityTaskFailed` – Failed to process ScheduleActivityTask decision. This happens when the decision isn’t configured properly, for example the activity type specified isn’t registered.

• ‘SignalExternalWorkflowExecutionFailed` – The request to signal an external workflow execution failed.

• ‘SignalExternalWorkflowExecutionInitiated` – A request to signal an external workflow was made.

• ‘StartActivityTaskFailed` – A scheduled activity task failed to start.

• ‘StartChildWorkflowExecutionFailed` – Failed to process StartChildWorkflowExecution decision. This happens when the decision isn’t configured properly, for example the workflow type specified isn’t registered.

• ‘StartChildWorkflowExecutionInitiated` – A request was made to start a child workflow execution.

• ‘StartTimerFailed` – Failed to process StartTimer decision. This happens when the decision isn’t configured properly, for example a timer already exists with the specified timer Id.

• ‘TimerCanceled` – A timer, previously started for this workflow execution, was successfully canceled.

• ‘TimerFired` – A timer, previously started for this workflow execution, fired.

• ‘TimerStarted` – A timer was started for the workflow execution due to a `StartTimer` decision.

• ‘WorkflowExecutionCancelRequested` – A request to cancel this workflow execution was made.

• ‘WorkflowExecutionCanceled` – The workflow execution was successfully canceled and closed.

• ‘WorkflowExecutionCompleted` – The workflow execution was closed due to successful completion.

• ‘WorkflowExecutionContinuedAsNew` – The workflow execution was closed and a new execution of the same type was created with the same workflowId.

• ‘WorkflowExecutionFailed` – The workflow execution closed due to a failure.

• ‘WorkflowExecutionSignaled` – An external signal was received for the workflow execution.

• ‘WorkflowExecutionStarted` – The workflow execution was started.

• ‘WorkflowExecutionTerminated` – The workflow execution was terminated.

• ‘WorkflowExecutionTimedOut` – The workflow execution was closed because a time out was exceeded.
