> Project: Flink
> Issue Type: Improvement
> Components: Table SQL / Runtime
> Reporter: Liya Fan

>
> The there are many classes in the class hierarchy of BinaryFormat. They share
> the same memory format:
> header + nullable bits + fixed length part + variable length part
> So many operations can be applied to a number of sub-classes. Currently, many
> such operations are implemented in each sub-class, although they implement
> identical functionality.
> This makes the code hard to understand and maintain.
> In this proposal, we refactor the class hierarchy, and move common operations
> into the base class, leaving only one implementation for each common
> operation.
