I'm having issues where a certain form of akka.util.ByteString isn't serializable (ByteString1). It is the sliced version of a ByteString based off of a byte array. I understand that wrapping a byte Array breaks the mutability guarantee and etc... but that is ignored sometimes with Arrays and such. ByteString's 'contract' states that it is an immutable object and and will never change... and that should be its end behavior. So I guess I don't understand why just this one form of ByteString doesnt serialize? If I cast the array to a Seq[Byte] using the java->scala implicits and concat that to a ByteString... it works fine (and as far as I know is still referencing the original array). I guess I always assumed that all immutable instances of Seq really should just serialize out (although I guess SeqView doesnt either, but thats a bit more specific). Any justification or clarification for me? The ByteString class itself isn't serializable. Only a subcategory called CompactByteString (things referencing a contiguous chunk of memory) is serializable. Why this difference was introduced isn't clear from the comments or the pull request. There is also the question of what it exactly means to serialize a ByteString. Do you expect it to become one big contiguous array automatically? One way to get something serializable is to compact your ByteString. I've opened a ticket to investigate this further https://github.com/akka/akka/issues/15170 B/ https://github.com/akka/akka/blob/master/akka-actor/src/main/scala/akka/util/ByteString.scala -- >>>>>>>>>> Read the docs: http://akka.io/docs/ >>>>>>>>>> Check the FAQ: >>>>>>>>>> http://doc.akka.io/docs/akka/current/additional/faq.html >>>>>>>>>> Search the archives: https://groups.google.com/group/akka-user --- You received this message because you are subscribed to the Google Groups "Akka User List" group.
