Method Details

getKey

@Stability(Stable)
@NotNull
Map<String,DynamoAttributeValue> getKey()

Primary key of the item to retrieve.

For the primary key, you must provide all of the attributes. For example, with a simple primary key, you only need to provide a value for the partition key. For a composite primary key, you must provide values for both the partition key and the sort key.
