Workflow Events

Description

Here is a typical CloudEvent example:

{
  "specversion" : "1.0",
  "id" : "018dcb5f-aab3-705b-b6a6-083581389dc8",
  "source" : "pulsar://localhost:6650/infinitic/test9/workflows/HelloWorkflow",
  "type" : "infinitic.workflow.taskCompleted",
  "datacontenttype" : "application/json",
  "subject" : "018dcb5f-a644-7a95-9375-ed68eb3082fb",
  "time" : "2024-02-21T11:14:20.964Z",
  "data" : {
    "taskCompleted" : {
      "result" : "Hello 0!",
      "taskId" : "018dcb5f-aa4e-7ce2-9e64-6ba78d282c1f",
      "taskName" : "addEnthusiasm",
      "serviceName" : "HelloService"
    },
    "methodId" : "018dcb5f-a644-7a95-9375-ed68eb3082fb",
    "methodName" : "greet",
    "workflowName" : "HelloWorkflow",
    "workflowVersion" : 0,
    "workerName" : "standalone-13907-104",
    "infiniticVersion" : ":0.16.1"
  }
}

For all workflow events:

id serves as a unique identifier for the event.
subject denotes the workflow's ID.
time indicates the publishing time of the event.
type is prefixed with infinitic.workflow.*, where * corresponds to one of the following:

CloudEvent's type postfix	Type	Description
`dispatch`	Command	A new workflow has been scheduled.
`dispatchMethod`	Command	A new method execution has been scheduled on an existing workflow.
`cancel`	Command	The cancellation of a workflow has been requested.
`cancelMethod`	Command	The cancellation of a workflow's method has been requested.
`retryTask`	Command	The retry of some tasks has been requested.
`retryExecutor`	Command	The retry of the workflow executor has been requested.
`signal`	Command	A signal has been sent to the workflow.
`signalReceived`	Event	The workflow has received a signal.
`signalDiscarded`	Event	The workflow has discarded a signal that was unexpected.
`signalDispatched`	Event	The workflow has sent a signal to another workflow.
`timerDispatched`	Event	The workflow has dispatched a timer.
`timerCompleted`	Event	A timer, used by the workflow, has completed.
`remoteMethodDispatched`	Event	The workflow has dispatched another workflow's method.
`remoteMethodCompleted`	Event	Another workflow's method, used by the workflow, has completed.
`remoteMethodFailed`	Event	Another workflow's method, used by the workflow, has failed.
`remoteMethodCanceled`	Event	Another workflow's method, used by the workflow, has been canceled.
`remoteMethodTimedOut`	Event	Another workflow's method, used by the workflow, has timed out.
`taskDispatched`	Event	The workflow has dispatched a task.
`taskCompleted`	Event	A task, used by the workflow, has completed successfully.
`taskFailed`	Event	A task, used by the workflow, has failed.
`taskTimedOut`	Event	A task, used by the workflow, has timed out.

The source property describes the Pulsar cluster, tenant, and namespaces, as well as the workflow's name. However this property does not represent an actual Pulsar topic, as the events originate from multiple internal topics.
