> Currently, Flink is serializing the schema for each Avro GenericRecord in the stream.
> This leads to a lot of overhead over the wire/disk + high serialization costs.
> Therefore, I'm proposing to improve the support for GenericRecord in Flink by shipping the schema to each serializer  through the AvroTypeInformation.
> Then, we can only support GenericRecords with the same type per stream, but the performance will be much better.
