Classes

NameDescription
Class Attribute

Class AttributeDoesNotExistException

The specified attribute does not exist.

Class BatchDeleteAttributesRequest

Container for the parameters to the BatchDeleteAttributes operation. Performs multiple DeleteAttributes operations in a single call, which reduces round trips and latencies. This enables Amazon SimpleDB to optimize requests, which generally yields better throughput.

The following limitations are enforced for this operation:

  • 1 MB request size
  • 25 item limit per BatchDeleteAttributes operation
Class BatchDeleteAttributesResponse

This is the response object from the BatchDeleteAttributes operation.

Class BatchPutAttributesRequest

Container for the parameters to the BatchPutAttributes operation. The BatchPutAttributes operation creates or replaces attributes within one or more items. By using this operation, the client can perform multiple PutAttribute operation with a single call. This helps yield savings in round trips and latencies, enabling Amazon SimpleDB to optimize requests and generally produce better throughput.

The client may specify the item name with the Item.X.ItemName parameter. The client may specify new attributes using a combination of the Item.X.Attribute.Y.Name and Item.X.Attribute.Y.Value parameters. The client may specify the first attribute for the first item using the parameters Item.0.Attribute.0.Name and Item.0.Attribute.0.Value, and for the second attribute for the first item by the parameters Item.0.Attribute.1.Name and Item.0.Attribute.1.Value, and so on.

Attributes are uniquely identified within an item by their name/value combination. For example, a single item can have the attributes { "first_name", "first_value" } and { "first_name", "second_value" }. However, it cannot have two attribute instances where both the Item.X.Attribute.Y.Name and Item.X.Attribute.Y.Value are the same.

Optionally, the requester can supply the Replace parameter for each individual value. Setting this value to true will cause the new attribute values to replace the existing attribute values. For example, if an item I has the attributes { 'a', '1' }, { 'b', '2'} and { 'b', '3' } and the requester does a BatchPutAttributes of {'I', 'b', '4' } with the Replace parameter set to true, the final attributes of the item will be { 'a', '1' } and { 'b', '4' }, replacing the previous values of the 'b' attribute with the new value.

This operation is vulnerable to exceeding the maximum URL size when making a REST request using the HTTP GET method. This operation does not support conditions using Expected.X.Name, Expected.X.Value, or Expected.X.Exists.

You can execute multiple BatchPutAttributes operations and other operations in parallel. However, large numbers of concurrent BatchPutAttributes calls can result in Service Unavailable (503) responses.

The following limitations are enforced for this operation:

  • 256 attribute name-value pairs per item
  • 1 MB request size
  • 1 billion attributes per domain
  • 10 GB of total user data storage per domain
  • 25 item limit per BatchPutAttributes operation
Class BatchPutAttributesResponse

This is the response object from the BatchPutAttributes operation.

Class CreateDomainRequest

Container for the parameters to the CreateDomain operation. The CreateDomain operation creates a new domain. The domain name should be unique among the domains associated with the Access Key ID provided in the request. The CreateDomain operation may take 10 or more seconds to complete.

The client can create up to 100 domains per account.

If the client requires additional domains, go to http://aws.amazon.com/contact-us/simpledb-limit-request/.

Class CreateDomainResponse

This is the response object from the CreateDomain operation.

Class DeletableItem

Class DeleteAttributesRequest

Container for the parameters to the DeleteAttributes operation. Deletes one or more attributes associated with an item. If all attributes of the item are deleted, the item is deleted.

DeleteAttributes is an idempotent operation; running it multiple times on the same item or attribute does not result in an error response.

Because Amazon SimpleDB makes multiple copies of item data and uses an eventual consistency update model, performing a GetAttributes or Select operation (read) immediately after a DeleteAttributes or PutAttributes operation (write) might not return updated item data.

Class DeleteAttributesResponse

This is the response object from the DeleteAttributes operation.

Class DeleteDomainRequest

Container for the parameters to the DeleteDomain operation. The DeleteDomain operation deletes a domain. Any items (and their attributes) in the domain are deleted as well. The DeleteDomain operation might take 10 or more seconds to complete.

Class DeleteDomainResponse

This is the response object from the DeleteDomain operation.

Class DomainMetadataRequest

Container for the parameters to the DomainMetadata operation. Returns information about the domain, including when the domain was created, the number of items and attributes in the domain, and the size of the attribute names and values.

Class DomainMetadataResponse

This is the response object from the DomainMetadata operation.

Class DuplicateItemNameException

The item name was specified more than once.

Class GetAttributesRequest

Container for the parameters to the GetAttributes operation. Returns all of the attributes associated with the specified item. Optionally, the attributes returned can be limited to one or more attributes by specifying an attribute name parameter.

If the item does not exist on the replica that was accessed for this operation, an empty set is returned. The system does not return an error as it cannot guarantee the item does not exist on other replicas.

Class GetAttributesResponse

This is the response object from the GetAttributes operation.

Class InvalidNextTokenException

The specified NextToken is not valid.

Class InvalidNumberPredicatesException

Too many predicates exist in the query expression.

Class InvalidNumberValueTestsException

Too many predicates exist in the query expression.

Class InvalidParameterValueException

The value for a parameter is invalid.

Class InvalidQueryExpressionException

The specified query expression syntax is not valid.

Class Item

Class ListDomainsRequest

Container for the parameters to the ListDomains operation. The ListDomains operation lists all domains associated with the Access Key ID. It returns domain names up to the limit set by MaxNumberOfDomains. A NextToken is returned if there are more than MaxNumberOfDomains domains. Calling ListDomains successive times with the NextToken provided by the operation returns up to MaxNumberOfDomains more domain names with each successive operation call.

Class ListDomainsResponse

This is the response object from the ListDomains operation.

Class MissingParameterException

The request must contain the specified missing parameter.

Class NoSuchDomainException

The specified domain does not exist.

Class NumberDomainAttributesExceededException

Too many attributes in this domain.

Class NumberDomainBytesExceededException

Too many bytes in this domain.

Class NumberDomainsExceededException

Too many domains exist per this account.

Class NumberItemAttributesExceededException

Too many attributes in this item.

Class NumberSubmittedAttributesExceededException

Too many attributes exist in a single call.

Class NumberSubmittedItemsExceededException

Too many items exist in a single call.

Class PutAttributesRequest

Container for the parameters to the PutAttributes operation. The PutAttributes operation creates or replaces attributes in an item. The client may specify new attributes using a combination of the Attribute.X.Name and Attribute.X.Value parameters. The client specifies the first attribute by the parameters Attribute.0.Name and Attribute.0.Value, the second attribute by the parameters Attribute.1.Name and Attribute.1.Value, and so on.

Attributes are uniquely identified in an item by their name/value combination. For example, a single item can have the attributes { "first_name", "first_value" } and { "first_name", second_value" }. However, it cannot have two attribute instances where both the Attribute.X.Name and Attribute.X.Value are the same.

Optionally, the requestor can supply the Replace parameter for each individual attribute. Setting this value to true causes the new attribute value to replace the existing attribute value(s). For example, if an item has the attributes { 'a', '1' }, { 'b', '2'} and { 'b', '3' } and the requestor calls PutAttributes using the attributes { 'b', '4' } with the Replace parameter set to true, the final attributes of the item are changed to { 'a', '1' } and { 'b', '4' }, which replaces the previous values of the 'b' attribute with the new value.

You cannot specify an empty string as an attribute name.

Because Amazon SimpleDB makes multiple copies of client data and uses an eventual consistency update model, an immediate GetAttributes or Select operation (read) immediately after a PutAttributes or DeleteAttributes operation (write) might not return the updated data.

The following limitations are enforced for this operation:

  • 256 total attribute name-value pairs per item
  • One billion attributes per domain
  • 10 GB of total user data storage per domain
Class PutAttributesResponse

This is the response object from the PutAttributes operation.

Class ReplaceableAttribute

Class ReplaceableItem

Class RequestTimeoutException

A timeout occurred when attempting to query the specified domain with specified query expression.

Class SelectRequest

Container for the parameters to the Select operation. The Select operation returns a set of attributes for ItemNames that match the select expression. Select is similar to the standard SQL SELECT statement.

The total size of the response cannot exceed 1 MB in total size. Amazon SimpleDB automatically adjusts the number of items returned per page to enforce this limit. For example, if the client asks to retrieve 2500 items, but each individual item is 10 kB in size, the system returns 100 items and an appropriate NextToken so the client can access the next page of results.

For information on how to construct select expressions, see Using Select to Create Amazon SimpleDB Queries in the Developer Guide.

Class SelectResponse

This is the response object from the Select operation.

Class TooManyRequestedAttributesException

Too many attributes requested.

Class UpdateCondition

Specifies the conditions under which data should be updated. If an update condition is specified for a request, the data will only be updated if the condition is satisfied. For example, if an attribute with a specific name and value exists, or if a specific attribute doesn't exist.
