Overview

Note:

When making an API call, you may pass GlobalSecondaryIndex data as a hash:

{
  index_name: "IndexName", # required
  key_schema: [ # required
    {
      attribute_name: "KeySchemaAttributeName", # required
      key_type: "HASH", # required, accepts HASH, RANGE
    },
  ],
  projection: { # required
    projection_type: "ALL", # accepts ALL, KEYS_ONLY, INCLUDE
    non_key_attributes: ["NonKeyAttributeName"],
  },
  provisioned_throughput: {
    read_capacity_units: 1, # required
    write_capacity_units: 1, # required
  },
}

Represents the properties of a global secondary index.

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.

#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.
