Re: [akka-user] Re: Akka cluster sharding messages default serialization

That is right, we use Protobuf for all Akka internal messages and
persistent events/snapshots.

[akka-user] Re: Akka cluster sharding messages default serialization

[Leonard Ehrenfried]

I'm going to answer my own question here.

It turns out that akka-cluster-sharding registers its own serializer which 
is based on protobuf. It's a bit hard to find because it's all private but 
here is it on 
Github: 
https://github.com/akka/akka/blob/master/akka-cluster-sharding/src/main/scala/akka/cluster/sharding/protobuf/ClusterShardingMessageSerializer.scala

I used this test to find out what the serializer 
is: https://gist.github.com/leonardehrenfried/99194ad1164049434d187a5b4068b008
