> Project: Flink
> Issue Type: Improvement

> Reporter: Liya Fan
> Assignee: Liya Fan
> Priority: Minor

> Since there are only 256 possible byte values, the largest possible range is
> 255, and the condition
> range < OptimizableHashSet.DENSE_THRESHOLD
> must be satisfied. So ByteHashSet must be in dense mode.
> We can make use of this to improve the performance and code structure.
