Merge

The event-merge processor, merges multiple event messages together based on some criteria.

Each gNMI subscribe Response Update in a gNMI subscribe Response Notification is transformed into an Event Message

The event-merge processor is used to merge the updates into one event message if it's needed.

The default merge strategy is based on the timestamp, the updates with the same timestamp will be merged into the same event message.

processors:
  # processor name
  sample-processor:
    # processor type
    event-merge:
      # if always is set to true, 
      # the updates are merged regardless of the timestamp values
      always: false
      debug: false
