Change Log Actor

The chglog actor places a record on a write queue. The record is then written to the Piper change log asynchronously.

The chglog task is a synchronous task as it places a record on a queue that is serviced by a write thread that is asynchronous to the flow processing.

There are no additional parameters to the chglog task actor. The task follows the first or only link to the next task. No link label is needed.

The JSON used to designate a chglog task in a flow description is:

    "task-x": {
        "actor": "chglog",
         "trace": false,
         "links": {
            "": "task-y"
