When you have configured a Materialized Feed, you can trigger the calculation of data feed results and the subsequent materialization of the results in the corresponding Terracotta dataset.
You cannot run this process multiple times in parallel for the same Materialized Feed. If you want to trigger a new run, you must wait until the current run is completed. Each time you start a new run, the contents of the dataset are deleted so that it contains only the results of the latest run.
You have various options for materializing data feed results.
