Method Detail

indexName

public String indexName()

Represents the name of the local secondary index.

Returns:

Represents the name of the local secondary index.

hasKeySchema

public boolean hasKeySchema()

Returns true if the KeySchema property was specified by the sender (it may be empty), or false if the sender did not specify the value (it will be empty). For responses returned by the SDK, the sender is the AWS service.

keySchema

public List<KeySchemaElement> keySchema()

The complete key schema for the local secondary index, consisting of one or more pairs of attribute names and key types:

• HASH - partition key

• RANGE - sort key

The partition key of an item is also known as its hash attribute. 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 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.

Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

You can use hasKeySchema() to see if a value was sent in this field.

Returns:

The complete key schema for the local secondary index, consisting of one or more pairs of attribute names and key types:

• HASH - partition key

• RANGE - sort key

The partition key of an item is also known as its hash attribute. 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 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.

projection

public Projection projection()

Represents attributes that are copied (projected) from the table into the global secondary index. These are in addition to the primary key attributes and index key attributes, which are automatically projected.

Returns:

Represents attributes that are copied (projected) from the table into the global secondary index. These are in addition to the primary key attributes and index key attributes, which are automatically projected.

indexSizeBytes

public Long indexSizeBytes()

The total size of the specified index, in bytes. DynamoDB updates this value approximately every six hours. Recent changes might not be reflected in this value.

Returns:

The total size of the specified index, in bytes. DynamoDB updates this value approximately every six hours. Recent changes might not be reflected in this value.

itemCount

public Long itemCount()

The number of items in the specified index. DynamoDB updates this value approximately every six hours. Recent changes might not be reflected in this value.

Returns:

The number of items in the specified index. DynamoDB updates this value approximately every six hours. Recent changes might not be reflected in this value.

indexArn

public String indexArn()

The Amazon Resource Name (ARN) that uniquely identifies the index.

Returns:

The Amazon Resource Name (ARN) that uniquely identifies the index.
