To access a dataset with Materialized Feed results on a Terracotta DB server, you have to configure a Terracotta DB connection and a Materialized Feed in MashZone NextGen in advance. Both can be defined in the MashZone NextGen Admin console. See Manage Terracotta DB connections and Manage Materialized Feeds.
Select Materialized Feed in the Source drop-down menu.
Select a Materialized Feed alias in the Materialized Feed drop-down menu. The selected alias specifies the Materialized Feed with the dataset containing the Materialized Feed results. The menu contains all available Materialized Feed aliases for which you have the Usage privilege. The corresponding dataset is displayed in Dataset Name box.
Configure the RAQL query, refresh rate, and input parameters. For details, see Terracotta DB data source.
