- 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.
