Trigger Schemas
The trigger event provides a status as ``UP`` or
``DOWN``. To avoid tests for these strings in the
- logic, we defined an Avro schema for an enumeration.
+ logic, we defined an Avro schema for an enumeration (|avroSchemaLinkStatus_link|).
This does not impact the trigger system (it can still
send the strings), but makes the task logic simpler.

Context Logic Nodes
--------------------
The node context logic simply takes the trigger event
(for context) and creates a new node in the local

sends the context events to APEX to initialize the
topology and the customers. Then it takes events from
Kafka and sends them to APEX.
