Tuning of the Cassandra read time via the DDS Data Set

Hi,

I am looking for a configuration to tune the read query time from the Cassandra table in Pega, while using the DDS Data Set to read the data from Cassandra. Is that possible by e.g. DSS configuration, or changing the yaml file? The client, that I am working for uses an on-premise installation with two Cassandra PODs (6 cores / 250GB each) configured, as the external DDSs (Decision Data Stores) in Pega. We are currently using a batch data flow run to read and aggregate ~150mln of the records from the Cassandra table and most of the data flow run time (~70%) Pega spends on a read operation from the DDS Data Set, so we would like to improve that read query time.

Really appreciate replies in that topic.
