final class UnsafeArrayData extends ArrayData with Externalizable with KryoSerializable

An Unsafe implementation of Array which is backed by raw memory instead of Java objects.

Each array has four parts: [numElements][null bits][values or offset&length][variable length portion]

The numElements is 8 bytes storing the number of elements of this array.

In the null bits region, we store 1 bit per element, represents whether an element is null Its total size is ceil(numElements / 8) bytes, and it is aligned to 8-byte boundaries.

In the values or offset&length region, we store the content of elements. For fields that hold fixed-length primitive types, such as long, double, or int, we store the value directly in the field. The whole fixed-length portion (even for byte) is aligned to 8-byte boundaries. For fields with non-primitive or variable-length values, we store a relative offset (w.r.t. the base address of the array) that points to the beginning of the variable-length field and length (they are combined into a long). For variable length portion, each is aligned to 8-byte boundaries.

Instances of UnsafeArrayData act as pointers to row data stored in this format.
