I want to use Akka.Cluster for simple user profile service. There will be few instances of http-api services witch will send messages for some backend instances with userprofile persistent actors(Profile Actor). Every http-api service can send message for same Profile Actor, so I should use Consistent Hashing Group router. But if I'll use group router, I should for every Profile Actor add route to group router, as I know, it's impossible. I can't use pool router, because every instance of http-api with pool router, will create his own Profile Actor for one user. How can I implement user's profile with akka.cluster? Maybe it's exist some patterns for same situations?

Solution 1: Akka Cluster Sharding will be useful. See at Cluster Sharding
Solution 2: Custom routing. This solution is simple to move to Akka.NET.

Thank you, but first solution not useful because it will one cluster shard with few nodes. About Custom routing is useful, but I don't like this solution because routers are specific actors with functionality of fast forwarding,simple actors are not so fast. – neftedollar Aug 26 '15 at 20:33

In first solution you can implement shardId() method in ShardRegion.MessageExtractor interface (valid for Java). This method is used to determine the number of shard. – Vers_us Aug 26 '15 at 22:21

Oh, I understand. It' cool but cluster sharding not yet exist in Akka.net – neftedollar Aug 27 '15 at 10:32
