Veena Basavaraj commented on SQOOP-1709:
----------------------------------------
the name "key" in this class actually means nested type. A key is a complex
data type usually has the meaning of "key" in a collection/map
{code}
/**
* Complex types that are incorporating primitive types.
*/
public abstract class AbstractComplexType extends Column {
/**
* Incorporated type
*/
private Column key;
public AbstractComplexType(Column key) {
setKey(key);
}
{code}
Am I correct that this infact is saying what is the nested type, for instance
if it is an array of integers, array of strings, or array of another complex
type?

> What is the use case for it to have a "key' as a Column type.
> This mean I could have the key as an Array / Map/ Flaoting point? when would
> this happen, can String not suffice for the key?
> I need details on this.
> Second, for good reasons, we should have a size field to support the
> collection size.
> Third, Make sure SchemaSerialization class is updated as well with these
> changes.
