-------------------------------------

Hey, [~StephanEwen] I would suggest this issue type probably not belongs to a bug. So, I changed
it to Improvement instead.

> Currently, the {{byte[]}} to object conversion and vice versa is always done by creating
new byte array streams and Data Input/Output streams. That is pretty wasteful, we can optimize
this with Flink's own classes:
>   - {{DataInputSerializer}}
>   - {{DataOutputSerializer}}
