public class AwsSchemaProvider extends GetterBasedSchemaProviderV2
SdkPojo models using the provided field metadata (@see SdkPojo.sdkFields()) rather than reflection.
Note: Beam doesn't support self-referential schemas. Some AWS models are not compatible with
schemas for that reason and require a dedicated coder, such as DynamoDB AttributeValue (coder).

Delegates to the

fieldValueTypeInformations(TypeDescriptor<?> targetTypeDescriptor,
Schema schema)
Delegates to the

fromRowFunction(TypeDescriptor<T> type)
Given a type, returns a function that converts from a
Row object to that type. |
<T> @Nullable Schema |
schemaFor(TypeDescriptor<T> type)
Lookup a schema for the given type.
