Response Elements

If the action is successful, the service sends back an HTTP 200 response.

The following data is returned in JSON format by the service.

TableDescription

The description of the table created from an existing backup.

Type: TableDescription object

Errors

For information about the errors that are common to all actions, see Common Errors.

BackupInUseException

There is another ongoing conflicting backup control plane operation on the table. The backup is either being created, deleted or restored to a table.

HTTP Status Code: 400

BackupNotFoundException

Backup not found for the given BackupARN.

HTTP Status Code: 400

InternalServerError

An error occurred on the server side.

HTTP Status Code: 500

LimitExceededException

There is no limit to the number of daily on-demand backups that can be taken.

For most purposes, up to 500 simultaneous table operations are allowed per account. These operations include CreateTable, UpdateTable, DeleteTable,UpdateTimeToLive, RestoreTableFromBackup, and RestoreTableToPointInTime.

When you are creating a table with one or more secondary indexes, you can have up to 250 such requests running at a time. However, if the table or index specifications are complex, then DynamoDB might temporarily reduce the number of concurrent operations.

When importing into DynamoDB, up to 50 simultaneous import table operations are allowed per account.

There is a soft account quota of 2,500 tables.

GetRecords was called with a value of more than 1000 for the limit request parameter.

More than 2 processes are reading from the same streams shard at the same time. Exceeding this limit may result in request throttling.

HTTP Status Code: 400

TableAlreadyExistsException

A target table with the specified name already exists.

HTTP Status Code: 400

TableInUseException

A target table with the specified name is either being created or deleted.

HTTP Status Code: 400
