Represents a single element 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.
KeySchemaElement represents exactly one attribute of the primary key.
For example, a simple primary key would be represented by one
(for the partition key). A composite primary key would require one
for the partition key, and another
KeySchemaElement for the sort key.
KeySchemaElement 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.
public class KeySchemaElement
The KeySchemaElement type exposes the following members
Gets and sets the property AttributeName.
The name of a key attribute.
Gets and sets the property KeyType.
The role that this key attribute will assume:
The partition key of an item is also known as its hash attribute. The term "hash attribute" derives from DynamoDB' 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 range attribute. 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.
