Anyone else using Avro and avro4s to serialize persistence events? I was able to get the SerializerWithStringManifest below working (with generic serialize and deserialize methods). Should I be extending something other than SerializerWithStringManifest, given that Avro on its own helps with schema evolution?
Note: avro4s seems very promising, although I did run into this limitation https://github.com/sksamuel/avro4s/issues/75 class PersistenceEventsAvroSerializer extends SerializerWithStringManifest { val FooManifest = "Foo" val BarManifest = "Bar" def identifier = 1234567 override def manifest(obj: AnyRef): String = obj match { case _: Bar => BarManifest case _: Foo => FooManifest } override def toBinary(obj: AnyRef): Array[Byte] = { obj match { case foo: Foo => serialize[Foo](foo) case bsr: Bar => serialize[Bar](bar) } } override def fromBinary(bytes: Array[Byte], manifest: String): AnyRef = { manifest match { case FooManifest => deserialize[Foo](bytes) case BarManifest => deserialize[Bar](bytes) } } private def serialize[T](data: T)(implicit s: SchemaFor[T], r: ToRecord[T]): Array[Byte] = { val baos = new ByteArrayOutputStream val output = AvroOutputStream.binary[T](baos) output.write(data) output.close() val result = baos.toByteArray() result } private def deserialize[T](data: Array[Byte])(implicit s: SchemaFor[T], r: FromRecord[T]): T = { val input = AvroInputStream.binary[T](data) val result: T = if (input.iterator.isEmpty) { ??? // TODO Check } else { input.iterator.toSeq.head } result } } -- >>>>>>>>>> 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.
