Materialized Feeds are used to calculate feed results and materialize them in a dataset which is managed by a Terracotta DB server. MashZone NextGen creates those datasets if not already present. MashZone NextGen can also delete them if required. In a few use cases deletion of those datasets is not possible:
If you want to delete these datasets, a Terracotta DB administrator must perform that task using Terracotta DB tooling.
Besides Materialized Feed datasets, MashZone NextGen also creates a dataset to maintain metadata associated with Materialized Feed datasets as well as runtime information. This metadata dataset must neither be manipulated nor deleted as it is required for the correct interaction of MashZone NextGen with Materialized Feed datasets.
