Question

Materialized IH Summaries - how do they work

Hi

Could you point me in the right direction and help to understand how these IH Summaries work please?

Specifically I need to understand how the Meterialized data sets are updated.

From what I understand, materialized data sets are precalculated and stored in Cassandra DDS?

But when new customer interaction occurs, how this materialized data set is updated then? Do we need to update it declaratively? Or is it updated automatically? How does it work?

Could you advise please?

Thanks
Andy

Materialized IH Summaries are automatically managed for you.  On initial materialization (bootstrap stage), the system scans IH to establish the starting point for the aggregation and stores the result in Cassandra.  As subsequent IH entries are captured, the data is automatically sent to the aggregation data set to keep the aggregation current and automatically managed.
