Instance Attribute Details

#index_name ⇒ String

The name of the global secondary index. The name must be unique among all other indexes on this table.

Returns:

• (String)

# File 'lib/aws-sdk-dynamodb/types.rb', line 4130

class GlobalSecondaryIndex < Struct.new(
  :index_name,
  :key_schema,
  :projection,
  :provisioned_throughput,
  :on_demand_throughput)
  SENSITIVE = []
  include Aws::Structure
end

#key_schema ⇒ Array<Types::KeySchemaElement>

The complete key schema for a global secondary index, which consists of one or more pairs of attribute names and key types:

• ‘HASH` - partition key

• ‘RANGE` - sort key

<note markdown=“1”> 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.

</note>

Returns:

• (Array<Types::KeySchemaElement>)

# File 'lib/aws-sdk-dynamodb/types.rb', line 4130

class GlobalSecondaryIndex < Struct.new(
  :index_name,
  :key_schema,
  :projection,
  :provisioned_throughput,
  :on_demand_throughput)
  SENSITIVE = []
  include Aws::Structure
end

#on_demand_throughput ⇒ Types::OnDemandThroughput

The maximum number of read and write units for the specified global secondary index. If you use this parameter, you must specify ‘MaxReadRequestUnits`, `MaxWriteRequestUnits`, or both.

Returns:

• (Types::OnDemandThroughput)

# File 'lib/aws-sdk-dynamodb/types.rb', line 4130

class GlobalSecondaryIndex < Struct.new(
  :index_name,
  :key_schema,
  :projection,
  :provisioned_throughput,
  :on_demand_throughput)
  SENSITIVE = []
  include Aws::Structure
end

#projection ⇒ Types::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:

• (Types::Projection)

# File 'lib/aws-sdk-dynamodb/types.rb', line 4130

class GlobalSecondaryIndex < Struct.new(
  :index_name,
  :key_schema,
  :projection,
  :provisioned_throughput,
  :on_demand_throughput)
  SENSITIVE = []
  include Aws::Structure
end

#provisioned_throughput ⇒ Types::ProvisionedThroughput

Represents the provisioned throughput settings for the specified global secondary index.

For current minimum and maximum provisioned throughput values, see

in the *Amazon DynamoDB

Developer Guide*.
