Thanks @TomF & @marc.dipasquale for the response.
@marc.dipasquale In the consumer application as per above , i can have binding on topic i.e, “spring.cloud.stream.function.bindings.handleControlMsg-in-0=command/topic/>” instead of the Solace binder which creates a queue that subscribes to this topic? If so then i am good with the solution. We’ll try to implement accordingly.
