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,
Akshay Aggarwal
