> Since interface {{RelDataTypeFactory.FieldInfo}} is deprecated, and {{RelDataTypeFactory.FieldInfoBuilder}} implements it, we should also deprecate {{FieldInfoBuilder}}.
> We will create a new class {{RelDataTypeFactory.Builder}} that does the same as {{FieldInfoBuilder}} without implementing the {{FieldInfo}} interface.
> For backwards compatibility, {{RelDataTypeFactory.builder()}} will continue to return {{FieldInfoBuilder}} but we recommend that you assign the result to a variable of type {{Builder}}. Thus you won't be using the deprecated class in your code.
