AdminWorkflowServices
Companion object AdminWorkflowServices
class AdminWorkflowServices extends FlagCloseableAsync with NamedLogging with Spanning with NoTracing
Manages our admin workflow applications (ping, dar distribution). Currently each is individual application with their own ledger connection and acting independently.
