We are trying to test the integration of Pega CDH with our External Kafka servers, but we have the constraint to use a well defined naming convention for the name of the topics. In particular they should begin with a fixed prefix for example "dev.sys.{stream.name}".

We have found that this can be achieved by adding the following line in the pronfig.xml file (or by creating a DSS):

<env name="services/stream/name/pattern" value="dev.sys.{stream.name}"/>

The problem is that, despite this configuration, Pega is still trying to create and to use some topics (the one associate to the dataset CDHResponseSource and pxInteractionsStream) without adding the previous prefix.

Can anyone help us?
