Overview

Represents the properties of a local secondary index.

  indexArn

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

@property (nonatomic, strong) NSString *indexArn

Declared In

AWSDynamoDBModel.h

  indexName

Represents the name of the local secondary index.

@property (nonatomic, strong) NSString *indexName

Declared In

AWSDynamoDBModel.h

  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.

@property (nonatomic, strong) NSNumber *indexSizeBytes

Declared In

AWSDynamoDBModel.h

  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.

@property (nonatomic, strong) NSNumber *itemCount

Declared In

AWSDynamoDBModel.h

  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.

@property (nonatomic, strong) NSArray<AWSDynamoDBKeySchemaElement*> *keySchema

Declared In

AWSDynamoDBModel.h

  projection

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

@property (nonatomic, strong) AWSDynamoDBProjection *projection
