Setting the flag to false had no effect, as I am using the spring boot starters and therefore the SpringEventRegistryEngineConfiguration. The spring implementation already sets the flag to false in its constructor and then unconditionally initializes the channel definitions in its Lifecyle.start() method.
I just discovered multi-schema tenancy is not supported in Spring Boot. Is it the auto-configuration in flowable’s spring boot starters that makes this incompatible? Would you recommend that I move away from the starter dependencies and create the process and event registry engines manually to achieve multi-schema tenancy?
