Hi there, not quite. If you use java serialization of X that contains Y things, then Java serialization serializes the entire thing. For example, if you serialized a List using java serialization, it also will serialize the things inside the list - that's how it works.
Akka always wraps your serialized message in a binary (protobuf serialized nowadays) envelope, the envelope contains your message, serialized using whichever serializer was configured for it. So with the List + Java example you'll end up with a java serialized list of java serialized items, within an akka envelope. Tips: a) Don't send around raw lists anyway, define proper message types - it's your message protocol, take good care of it. b) Define a good serializer for your messages. You can start out with akka-kryo-serialization, it's simple to set up, pretty fast etc. -- Konrad `ktoso` Malawski Akka <http://akka.io> @ Lightbend <http://lightbend.com> On 6 September 2016 at 08:33:36, Viktor Klang (viktor.kl...@gmail.com) wrote: Akka encloses the binary data in an envelope to track message size. It is recommended to send small messages for the same reason it is recommended to to send huge packets through normal post boxes. :-) -- Cheers, √ On Sep 6, 2016 08:00, "Wei" <weix...@gmail.com> wrote: > Hello, > > I am trying to write a custom serializer in akka.
