> Before carbon 2.0, complex child length is stored as SHORT for string,
> varchar, binary, date, decimal types.
> So, In 2.0 as it is stored as INT, presto complex query code always assumes
> it as INT
> and goes to out of bound exception when old store is queried.
>
> If INT_LENGTH_COMPLEX_CHILD_BYTE_ARRAY encoding is present, parse as INT,
> else parse as SHORT.
> so, that both stores can be queried.
