The key in which this value will be persisted in DynamoDB. If not provided, the key will be assumed to be the same in the input and in the persisted record.
An optional default value factory. If a type has a defined
defaultProvider and its value is undefined in the provided input, the
defaultProvider will be called and its return value serialized.
The behavior the marshaller should exhibit when it encounters "empty"
data that would be rejected as invalid by DynamoDB, such as 0-length
buffers or the string ''.
The behavior the marshaller should exhibit when it encounters data that cannot be marshalled to a DynamoDB AttributeValue, such as a Symbol or Function object.
Whether numbers should be unmarshalled to a special object type that can preserve values that would lose precision if converted to JavaScript's native number type.
A node used to store values whose type is variable or unknown. The value will be marshalled an unmarshalled based on runtime type detection, which may result in data not being precisely round-tripped (e.g., "empty" types such as zero-length strings, buffers, and sets will be returned from the mapper as
nullrather than an empty instance of the originally submitted type).
