Specifying ClusterSingletonManagerSettings programatically in typed not possible

[johanandren]

I could be missing something but I can't find anywhere it is possible to specify akka.cluster.typed.ClusterSingletonManagerSettings when setting up a typed singleton. We do have API in typed sharding accepting it to configure the coordinator singleton though.

SingletonActor has withSettings

That accepts akka.cluster.typed.ClusterSingletonSettings not akka.cluster.typed.ClusterSingletonManagerSettings. We could maybe add an optional managerSettings to the akka.cluster.typed.ClusterSingletonSettings for minimal impact.

Quite confusing, there seems to be some overlap between the two settings classes as well (role, removalMargin,handoverInterval) but other settings are only in either of them (leaseSettings, singletonName, bufferSize, singletonIdentificationInterval)

I see, what is it you are missing in ClusterSingletonSettings that would be defined in the ClusterSingletonManagerSettings?

I don't know exactly, but in classic if had a clear separation between proxy and manager, which we collapsed in Typed, but I'm not sure why we have ClusterSingletonManagerSettings. Maybe something with sharding as well.

[johanandren]

So we should maybe just add the settings that are in ClusterSingletonManagerSettings to ClusterSingletonSettings instead.

For the record the specific use case that lead to opening this issue was to be able to specify lease settings for a specific singleton.

Not sure what I was talking about, leaseSettings are in akka.cluster.typed.ClusterSingletonSettings, not sure any of the others are important to programatically configure.
