class Aws::DynamoDB::Types::LocalSecondaryIndexDescription

Represents the properties of a local secondary index.

@!attribute [rw] index_name

Represents the name of the local secondary index.
@return [String]

@!attribute [rw] key_schema

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

<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.

@return [Array<Types::KeySchemaElement>]
