Instance Attribute Details

#backfilling ⇒ Boolean

Indicates whether the index is currently backfilling. Backfilling is the process of reading items from the table and determining whether they can be added to the index. (Not all items will qualify: For example, a partition key cannot have any duplicate values.) If an item can be added to the index, DynamoDB will do so. After all items have been processed, the backfilling operation is complete and ‘Backfilling` is false.

You can delete an index that is being created during the ‘Backfilling` phase when `IndexStatus` is set to CREATING and `Backfilling` is true. You can’t delete the index that is being created when ‘IndexStatus` is set to CREATING and `Backfilling` is false.

<note markdown=“1”> For indexes that were created during a ‘CreateTable` operation, the `Backfilling` attribute does not appear in the `DescribeTable` output.

</note>

Returns:

  • (Boolean)

#index_status ⇒ String

The current state of the global secondary index:

  • ‘CREATING` - The index is being created.

  • ‘UPDATING` - The index is being updated.

  • ‘DELETING` - The index is being deleted.

  • ‘ACTIVE` - The index is ready for use.

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.
