Disabling the Decision Data Store as action state storage on Pega Cloud
New deployments of Pega Customer Decision Hub on Pega Cloud services are configured to use the Decision Data Store (DDS) to store action state. The DDS data sets manage large and active data from different sources and make it available for real-time and batch processing.
When the DDS is used to store action data, the following features are disabled:- Volume Constraints
- Wait volume overlays
- Campaign run restarts
- Direct output to template
- Prospects
If you want to use these features, you need to disable the DDS as action state storage, and then configure the campaigns and scheduled runs to write data to database tables.
