@timob , I will look into adding selectors, but the CCSMP wrapper is is meant to be a reference implementation for you to get started and Iam sure more needs done before its deployable. Besides, as @Aaron mentioned, use of selector pattern for message filtering is not generally recommended - unless you have specific usecase that can’t be met with topic routing. Message selectors bury the filtering in the application code and not performant compared to topic routing.
