MQTT protocol
The MQTT protocol provides a method for loading JSON data in HCL OneDB™.
The MQTT protocol is a light-weight messaging protocol that you can use to load data from devices or sensors. For example, you can use the MQTT protocol to publish data from sensors into a time series table.
When you define the wire listener type as mqtt
, you can insert JSON documents to
the database by sending PUBLISH packets. The MQTT wire listener does not support querying data with
SUBSCRIBE packets.
