Data persistence

Overview​

This addon automatically stores data that hasn't already been sent to the cloud in case of network or power loss.

How it works​

Connhex Edge works through a message queue: services can use its APIs to post a message to the queue, then it gets emptied as data is sent to the remote Connhex instance. The queue is in RAM though: in case of power loss, messages on the queue itself will get lost.

This addon provides persistence to the queue and adds a bit of logic around it. For example, as soon as the power comes back, all the pending messages will be synced to the cloud.

Requirements​

  • Connhex Edge: >= v1.1.0
  • For supported architectures and minimum hardware requirements, see here.
