com.amazonaws.services.dynamodb.model.KeySchemaElement

KeySchemaElement is the primary key (hash or hash-and-range) structure for the table.
com.amazonaws.services.dynamodbv2.model.KeySchemaElement

Represents a key schema. Specifies the attributes that make up the primary key of a table, or the key attributes of a secondary index.
