You shouldn't make instances of this class. Each attribute should be used as a named argument in the calls that expect this type of object. As an example, if Att1 is expected to be a Paws::DynamoDBStreams::KeySchemaElement object: $service_obj->Method(Att1 => { AttributeName => $value, ..., KeyType => $value }); =head3 Results returned from an API call Use accessors for each attribute. If Att1 is expected to be an Paws::DynamoDBStreams::KeySchemaElement object: $result = $service_obj->Method(...); $result->Att1->AttributeName =head1 DESCRIPTION Represents I of a key schema. A key schema specifies the attributes that make up the primary key of a table, or the key attributes of an index. A C represents exactly one attribute of the primary key. For example, a simple primary key would be represented by one C (for the partition key). A composite primary key would require one C for the partition key, and another C for the sort key. A C must be a scalar, top-level attribute (not a nested attribute). The data type must be one of String, Number, or Binary. The attribute cannot be nested within a List or a Map. =head1 ATTRIBUTES =head2 B AttributeName => Str The name of a key attribute. =head2 B KeyType => Str The role that this key attribute will assume: =over =item * C - partition key =item * C - sort key =back The partition key of an item is also known as its I. The term "hash attribute" derives from DynamoDB's usage of an internal hash function to evenly distribute data items across partitions, based on their partition key values. The sort key of an item is also known as its I. The term "range attribute" derives from the way DynamoDB stores items with the same partition key physically close together, in sorted order by the sort key value. =head1 SEE ALSO This class forms part of L, describing an object used in L =head1 BUGS and CONTRIBUTIONS The source code is located here: L Please report bugs to: L =cut
