Does an identity mapper perform deserialization/serialization?

Hey,

I have a use case wherein I have to apply reduce function on a dataset
multiple times, and the data is stored in Avro Key Value Format.

I believe an identity mapper performs deserialization/serialization of the
data? If so is there a way to bypass it?

Thanks,
