Marley is a library for serialising Scrooge generated classes representing Thrift objects as Avro with minimal boilerplate.

libraryDependencies ++= Seq(
  "com.gu" %% "marley" % "0.2.16"
)

import com.gu.marley._

implicit val enumSer = AvroSerialisable.enum[ExampleEnum]
implicit val structSer = AvroSerialisable.struct[ExampleStruct]

AvroFile.write(Seq(struct))(file)

val readStructs: Iterable[ExampleStruct] = AvroFile.read[ExampleStruct](file)

Marley has been used successfully in the Guardian's realtime analytics system Ophan for many years.

Marley is macro based and doesn't perform any runtime reflection. I haven't done any micro-benchmarking, but it's currently serialising more than 5000 reasonably complicated messages/minute on an EC2 t2.medium without breaking a sweat.
