描述

For regular typed sharding we use a field of Entity but a sharded daemon process isn't using the Entity API.

研究方向
The issue requests a feature to allow custom shard allocation strategies for ShardedDaemonProcess, similar to entity sharding. Currently, ShardedDaemonProcess does not use the Entity API and thus does not support custom allocation. To implement, one should study how entity sharding allows custom allocation (via ShardAllocationStrategy) and adapt ShardedDaemonProcess to accept a similar parameter. The referenced discussion at https://discuss.lightbend.com/t/distribution of shardeddaemonprocess actors/9628 may provide additional context. The Akka codebase in akka cluster sharding typed likely holds relevant source files such as ShardedDaemonProcess.scala and related classes.
