"""Links the Request ID from the Source service to the Request ID returned
from the Target service.
Linkages are logged and emitted as INFO notifications.
:params context: context object
:params source_id: the Request ID of the source
:params target_id: the Request ID of the target
:params stage: optional event name extension to indicate which part of the
linkage this is.
:params target_name: human readable name of the target system you are
talking to.
:params notifier: notifier object
A typical use case is: System A asking System B to perform some action. The
linkages might look like this:
.. code-block:: python
link_request_ids(sys_A.request_ID, stage="start")
# send request to System B and get request ID
link_request_ids(sys_A.request_ID, target_id=sys_B.request.ID)
# optionally wait for System B to complete
link_request_ids(sys_A.request_ID, target_id=sys_B.request.ID,
stage="end")
But, it could be as simple as:
.. code-block:: python
link_request_ids(sys_A.request_ID, target_id=sys_B.request.ID)
