@PublicEvolving public final class UnresolvedDataType extends Object implements AbstractDataType<UnresolvedDataType>
LogicalType
.
Users are able to influence the nullability and conversion class even if the actual LogicalType
is not fully known yet. The information is stored and verified when resolving to
DataType
lazily.

A supported conversion class depends on the logical type and its nullability property.
Please see the implementation of LogicalType.supportsInputConversion(Class)
,
