We would still need to validate it before every ontrigger because what if the connection dropped. I guess we could validate it during onSchedule aswell and throw if it couldnt connect then, but would that prohibit the processor to start indefinetly or its rescheduled by the scheduler sometime in the future? (e.g. intermittent connection issue during onSchedule shouldnt break the flow imho) -- This is an automated message from the Apache Git Service.
