gvametapublish

Publishes the JSON metadata to MQTT or Kafka message brokers or files. MQTT and Kafka methods offer reconnection in case a connection to the broker is not established or is lost. During this reconnection time, any metadata that passes through the element will not be cached or published. It will simply pass through to the next element in the pipeline.
