table [required]

object

AttributeDefinitions

[object]

An array of AttributeDefinition objects. Each of these objects describes one attribute in the table and index key schema. Each AttributeDefinition object in this array is composed of:
AttributeName - The name of the attribute.
AttributeType - The data type for the attribute.

AttributeName [required]

string

A name for the attribute.

AttributeType [required]

string

The data type for the attribute, where:
S - the attribute is of type String
N - the attribute is of type Number
B - the attribute is of type Binary

TableName

string

The name of the table.

KeySchema

[object]

The primary key structure for the table. Each KeySchemaElement consists of:
AttributeName - The name of the attribute.
KeyType - The role of the attribute:
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'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.
For more information about primary keys, see Primary Key in the Amazon DynamoDB Developer Guide.

AttributeName [required]

string

The name of a key attribute.

KeyType [required]

string

The role that this key attribute will assume:
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'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.

TableStatus

string

The current state of the table:
CREATING - The table is being created.
UPDATING - The table is being updated.
DELETING - The table is being deleted.
ACTIVE - The table is ready for use.
INACCESSIBLE_ENCRYPTION_CREDENTIALS - The KMS key used to encrypt the table in inaccessible. Table operations may fail due to failure to use the KMS key. DynamoDB will initiate the table archival process when a table's KMS key remains inaccessible for more than seven days.
ARCHIVING - The table is being archived. Operations are not allowed until archival is complete.
ARCHIVED - The table has been archived. See the ArchivalReason for more information.

CreationDateTime

Tables with one or more local secondary indexes are subject to an item collection size limit, where the amount of data within a given item collection cannot exceed 10 GB. Each element is composed of:
IndexName - The name of the local secondary index.
KeySchema - Specifies the complete index key schema. The attribute names in the key schema must be between 1 and 255 characters (inclusive). The key schema must begin with the same partition key as the table.
Projection - Specifies attributes that are copied (projected) from the table into the index. These are in addition to the primary key attributes and index key attributes, which are automatically projected. Each attribute specification is composed of:
ProjectionType - One of the following:
KEYS_ONLY - Only the index and primary keys are projected into the index.
INCLUDE - Only the specified table attributes are projected into the index. The list of projected attributes is in NonKeyAttributes.
ALL - All of the table attributes are projected into the index.
NonKeyAttributes - A list of one or more non-key attribute names that are projected into the secondary index. The total count of attributes provided in NonKeyAttributes, summed across all of the secondary indexes, must not exceed 20. If you project the same attribute into two different indexes, this counts as two distinct attributes when determining the total.
IndexSizeBytes - Represents the total size of the index, in bytes. DynamoDB updates this value approximately every six hours. Recent changes might not be reflected in this value.

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.
