FairCom Edge MQTT Operation Support

FairCom Edge supports the MQTT operations listed in the table below:

MQTT Topic	Operation	c-tree Actions
ctreeAdministration	CreatePersistenceTopic	Creates a handler in the FairCom MQTT Broker that listens for MQTT messages that have been published to a specific topic. The handler processes the JSON document that is the payload of these MQTT messages. Creates a table in the ctree database to store data sent to that topic. Maps properties in the JSON document to fields in the table.
ctreeAdministration	AlterPersistenceTopic	Updates the handler, mapping, and table for the specified MQTT topic.
ctreeAdministration	RenamePersistenceTopic	Changes the name of an existing Persistence Topic.
ctreeAdministration	DeletePersistenceTopic	Deletes the handler for the specified MQTT topic, but retains the table and its data.
ctreeAdministration	PausePersistenceTopic	Stops the handler from processing incoming data messages with the given MQTT topic. It does not persist their data, but it can continue to pass messages on to subscribers (if it is configured to do so).
ctreeAdministration	ResumePersistenceTopic	Causes the handler to resume persisting data.
