Use the procedure below to add and configure a tUniqRow component that will be used to identify duplicate email addresses.

Procedure

  1. Next the tFileInputDelimited component, add a new addComponent {} function and its sub-function setComponentDefinition {} to add the tUniqRow component. 
    addComponent {
	setComponentDefinition {
		TYPE: "tUniqRow",
		NAME: "tUniqRow_1",
		POSITION: 416, 192
	}

}
  2. Next to the setComponentDefinition {} function, enter the setSettings {} function to define the deduplication process and label the component. 
    	setSettings {
		UNIQUE_KEY {
			SCHEMA_COLUMN : "email",
			KEY_ATTRIBUTE : "true"
		},
		LABEL : "deduplicate"
	}
  3. Next to the setSettings {} function, enter two addSchema {} functions to define the schemas for the output flows, one for the unique emails addresses and the other for the duplicates. 
    	addSchema {
		NAME: "UNIQUE",
		CONNECTOR: "UNIQUE"
		addColumn {
			NAME: "email",
			TYPE: "id_String"
		}
	}
	addSchema {
		NAME: "DUPLICATE",
		CONNECTOR: "DUPLICATE"
		addColumn {
			NAME: "email",
			TYPE: "id_String"
		}
	}
