MQTT Recorder requires that a database be set up in Ignition. That can be done as described in the 'Connect to a Database' section here.  Note Ignition supports additional database types.  Once a database is set up, MQTT Recorder can be configured.  Do so by opening the Ignition Gateway Web UI and browsing to the Configure tab at the top of the screen and then selecting 'MQTT Recorder Settings' as shown in the lower left below.

At this point the EFM ABB Totalflow driver is configured and is polling for history data at the rate specified in the EFM ABB Totalflow device configuration.  

MQTT Transmission is connected to the MQTT Server and as a result MQTT Engine is receiving tag change events.  In addition, because an EFM ABB Totalflow device has been created and configured with the same Sparkplug Group ID, Edge Node ID, and Device ID, history data will also be pushed to the MQTT server as Sparkplug RECORD objects.  When new history data is polled by the EFM ABB Totalflow driver, they will be published to the MQTT server, consumed by MQTT Engine, passed on to MQTT Recorder, and then inserted into the specified database.  Below are a few views of some history records using a third party database viewing tool.
