Constructor Detail
- PageBuilder
```
public PageBuilder(List<? extends Type> types)
```
  Create a PageBuilder with given types.
  A PageBuilder instance created with this constructor has no estimation about bytes per entry, therefore it can resize frequently while appending new rows.
  This constructor should only be used to get the initial PageBuilder. Once the PageBuilder is full use reset() or createPageBuilderLike() to create a new PageBuilder instance with its size estimated based on previous data.
