Response Structure

  • (dict) –

    • BackupDescription (dict) –

      Contains the description of the backup created for the table.

      • BackupDetails (dict) –

        Contains the details of the backup created for the table.

        • BackupArn (string) –

          ARN associated with the backup.

        • BackupName (string) –

          Name of the requested backup.

        • BackupSizeBytes (integer) –

          Size of the backup in bytes. DynamoDB updates this value approximately every six hours. Recent changes might not be reflected in this value.

        • BackupStatus (string) –

          Backup can be in one of the following states: CREATING, ACTIVE, DELETED.

        • BackupType (string) –

          BackupType:

          • USER - You create and manage these using the on-demand backup feature.

          • SYSTEM - If you delete a table with point-in-time recovery enabled, a SYSTEM backup is automatically created and is retained for 35 days (at no additional cost). System backups allow you to restore the deleted table to the state it was in just before the point of deletion.

          • AWS_BACKUP - On-demand backup created by you from Backup service.

        • BackupCreationDateTime (datetime) –

          Time at which the backup was created. This is the request time of the backup.

        • BackupExpiryDateTime (datetime) –

          Time at which the automatic on-demand backup created by DynamoDB will expire. This SYSTEM on-demand backup expires automatically 35 days after its creation.

      • SourceTableDetails (dict) –

        Contains the details of the table when the backup was created.

        • TableName (string) –

          The name of the table for which the backup was created.

        • TableId (string) –

          Unique identifier for the table for which the backup was created.

        • TableArn (string) –

          ARN of the table for which backup was created.

        • TableSizeBytes (integer) –

          Size of the table in bytes. Note that this is an approximate value.

        • KeySchema (list) –

          Schema of the table.

          • (dict) –

            Represents a single element of a key schema. A key schema specifies the attributes that make up the primary key of a table, or the key attributes of an index.

            A KeySchemaElement represents exactly one attribute of the primary key. For example, a simple primary key would be represented by one KeySchemaElement (for the partition key). A composite primary key would require one KeySchemaElement for the partition key, and another KeySchemaElement for the sort key.

            A KeySchemaElement must be a scalar, top-level attribute (not a nested attribute). The data type must be one of String, Number, or Binary. The attribute cannot be nested within a List or a Map.

            • AttributeName (string) –

              The name of a key attribute.

            • KeyType (string) –

              The role that this key attribute will assume:

              • HASH - partition key

              • RANGE - sort key

              Note

              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.

        • TableCreationDateTime (datetime) –

          Time when the source table was created.

        • ProvisionedThroughput (dict) –

          Read IOPs and Write IOPS on the table when the backup was created.

          • ReadCapacityUnits (integer) –

            The maximum number of strongly consistent reads consumed per second before DynamoDB returns a ThrottlingException. For more information, see Specifying Read and Write Requirements in the Amazon DynamoDB Developer Guide.

          • WriteCapacityUnits (integer) –

            The maximum number of writes consumed per second before DynamoDB returns a ThrottlingException. For more information, see Specifying Read and Write Requirements in the Amazon DynamoDB Developer Guide.

          • MaxReadRequestUnits (integer) –

            Maximum number of read request units for the specified table.

            To specify a maximum OnDemandThroughput on your table, set the value of MaxReadRequestUnits as greater than or equal to 1. To remove the maximum OnDemandThroughput that is currently set on your table, set the value of MaxReadRequestUnits to -1.

          • MaxWriteRequestUnits (integer) –

            Maximum number of write request units for the specified table.

            To specify a maximum OnDemandThroughput on your table, set the value of MaxWriteRequestUnits as greater than or equal to 1. To remove the maximum OnDemandThroughput that is currently set on your table, set the value of MaxWriteRequestUnits to -1.

        • ItemCount (integer) –

          Number of items in the table. Note that this is an approximate value.

        • BillingMode (string) –

          Controls how you are charged for read and write throughput and how you manage capacity. This setting can be changed later.

          • PROVISIONED - Sets the read/write capacity mode to PROVISIONED. We recommend using PROVISIONED for predictable workloads.

          • PAY_PER_REQUEST - Sets the read/write capacity mode to PAY_PER_REQUEST. We recommend using PAY_PER_REQUEST for unpredictable workloads.

      • SourceTableFeatureDetails (dict) –

        Contains the details of the features enabled on the table when the backup was created. For example, LSIs, GSIs, streams, TTL.

        • LocalSecondaryIndexes (list) –

          • (dict) –

            Represents the properties of a local secondary index for the table when the backup was created.

            • IndexName (string) –

              Represents the name of the local secondary index.

            • KeySchema (list) –

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

              • HASH - partition key

              • RANGE - sort key

            • Projection (dict) –

              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.

              • ProjectionType (string) –

                The set of attributes that are projected into the index:

                • KEYS_ONLY - Only the index and primary keys are projected into the index.

                • INCLUDE - In addition to the attributes described in KEYS_ONLY, the secondary index will include other non-key attributes that you specify.

                • ALL - All of the table attributes are projected into the index.

                When using the DynamoDB console, ALL is selected by default.

              • NonKeyAttributes (list) –

                Represents the non-key attribute names which will be projected into the index.

                For local secondary indexes, the total count of NonKeyAttributes summed across all of the local secondary indexes, must not exceed 100. If you project the same attribute into two different indexes, this counts as two distinct attributes when determining the total.
