Join Processor
The Join processor allows you to combine the output for multiple inputs. When multiple input processors are connected to a Join Processor, you must define the connector.
- Output mode
- Two options available here are map and array form
- Map option is better if standard JSON format is needed (eg. for Database output)
- Array option is better if all values are needed in an array format
- Map Field Prefix
- This field can remain empty, but you can add a prefix if you want, in front of the output fields when they are combined
- Array Sort Order
- In array mode, you can chose to arrange field values in either Ascending and Descending order
- Input Source
- What to show as the input source? Device Name, or the connecting wire definition name?
- If Device Name is chosen, it is required to have "deviceName" and "tagName" field in the input
