public String indexName()
The name of the local secondary index. The name must be unique among all other indexes on this table.
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' 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.

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