Pega Customer Decision Hub 8.5 adds new interaction history summaries, which are shipped without preaggregated data. To save processing time, turn on preaggregation for each interaction history summary by materializing them.

Preaggregated data sets save processing time because they include the latest interactions. Data sets that are not preaggregated do not include the latest interactions and therefore they query the database.

Pega Customer Decision Hub Update Guide
Before you begin: If you use an Oracle database for interaction history, update the column definitions for DateTime properties to use the TIMESTAMP datatype instead of the DATE datatype. For more information, see Modifying column definitions to use the TIMESTAMP data type in an Oracle database.
  1. Log in as an operator with access to the Summaries landing page.
    Access to the Summaries landing page is limited to users whose access group includes the CustomerDecisionHub:DataAdmin user role. For more information, see Granting access to the Data menu, data flows, and interaction history summaries.
  2. In App Studio, click DataSummaries.
  3. On the Summaries landing page, find the data set for which you want to turn on preaggregation, and click MoreMaterialized.
