Use Decision Date Store flag not affecting contact summary
After selecting the option "Use Decision Date Store" in the marking portal the customer summary records are still written to the RDBMS table <ext mkt schema>.mkt_contact_summary rather than than been applied to Cassandra. It looks like this flag is not altering the application to use Cassandra (DDS).
Steps to Reproduce
Run a Pega Marketing Campaign with 'Use decision data store' set.
Inspect the mkt_contact_summary table to check that records still getiing inserted.
To write the contanct summary data to the DDS it is requied to update the DF_OfferResults Data Flow as detailed in the Pega Marketing implementation guide (v.7.22).
See the section "Extending and updating the OfferResults data flow"
It is advised to use the database to store contact summary data.
In the upcoming release of Pega Marketing 7.31, we are moving away from storing Contact Policy data in the DDS (Cassandra).
So, regardless of the Use Decision Data Store application setting, the system will read and write Contact Policy data from the database.
