Hi all, The ClusterClient is designed to connect to a single ClusterReceptionist. When a cluster node running a receptionist gracefully leaves the cluster (i.e., because the node is shutting down), the cluster clients connected to that receptionist will keep sending message to it until the failure detector actually detects a failure. Detecting the failure can take quite long, depending on the configured heartbeat-interval and acceptable-heartbeat-pause (by default, up to 15 seconds).
In the case of a graceful shutdown of the cluster receptionist, couldn't we make the cluster client switch to another receptionist much faster? There are a couple ways we could do that, but I feel the most elegant would require to modify ClusterClient and ClusterReceptionist. Here's what I tried... I'm wondering if there's an interest in discussing/improving it for inclusion upstream, I could create an issue/PR if there's interest. I've created a new message: ClusterReceptionist.Internal.ReceptionistShutdown. When a receptionist detects that the node it is running on is removed from the cluster, in addition to stopping itself, it sends the ReceptionistShutdown message to all clients which interacted (using ClusterReceptionist.clientInteractions). When a cluster client get the ReceptionistShutdown message from the receptionist it is currently connect to, it behaves as if a failure had been detected, effectively looking for another receptionist to connect to. Should I do a PR out of this? Are there better ways?
