The "LoadBalancer" you see mentioned in the cs_cluster.log is not the traditional user-request routing load balancer used outside the TDV cluster. It is the internal TDV coordinator used to manage trigger-based requests
For each internal request (originating from a trigger), the TDV cluster time-keeper will call this internal "LoadBalancer" to decide which of the cluster node members should process the request. This is done when a trigger is configured to fire only once per cluster.
The cluster log's use of the word "LoadBalancer" isn't equivalent to the better known external request router and shouldn't be assumed as one. There is no need for TDV administrators to service or manage the "LoadBalancer" entity mentioned in our cluster log.
