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
sourcefn batch_put_attributes<'life0, 'async_trait>(

'life0: 'async_trait,
Self: 'async_trait,
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.
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
sourcefn create_domain<'life0, 'async_trait>(
&'life0 self,
input: CreateDomainRequest
) -> Pin<Box<dyn Future<Output = Result<(), RusotoError<CreateDomainError>>> + Send + 'async_trait>> where
'life0: 'async_trait,
Self: 'async_trait,
fn create_domain<'life0, 'async_trait>(
&'life0 self,
input: CreateDomainRequest
) -> Pin<Box<dyn Future<Output = Result<(), RusotoError<CreateDomainError>>> + Send + 'async_trait>> where
'life0: 'async_trait,
Self: 'async_trait,
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/.
sourcefn delete_attributes<'life0, 'async_trait>(
&'life0 self,
input: DeleteAttributesRequest
) -> Pin<Box<dyn Future<Output = Result<(), RusotoError<DeleteAttributesError>>> + Send + 'async_trait>> where
'life0: 'async_trait,
Self: 'async_trait,
fn delete_attributes<'life0, 'async_trait>(
&'life0 self,
input: DeleteAttributesRequest
) -> Pin<Box<dyn Future<Output = Result<(), RusotoError<DeleteAttributesError>>> + Send + 'async_trait>> where
'life0: 'async_trait,
Self: 'async_trait,
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.
sourcefn delete_domain<'life0, 'async_trait>(
&'life0 self,
input: DeleteDomainRequest
) -> Pin<Box<dyn Future<Output = Result<(), RusotoError<DeleteDomainError>>> + Send + 'async_trait>> where
'life0: 'async_trait,
Self: 'async_trait,
fn delete_domain<'life0, 'async_trait>(
&'life0 self,
input: DeleteDomainRequest
) -> Pin<Box<dyn Future<Output = Result<(), RusotoError<DeleteDomainError>>> + Send + 'async_trait>> where
'life0: 'async_trait,
Self: 'async_trait,
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.
sourcefn domain_metadata<'life0, 'async_trait>(
&'life0 self,
input: DomainMetadataRequest
) -> Pin<Box<dyn Future<Output = Result<DomainMetadataResult, RusotoError<DomainMetadataError>>> + Send + 'async_trait>> where
'life0: 'async_trait,
Self: 'async_trait,
fn domain_metadata<'life0, 'async_trait>(
&'life0 self,
input: DomainMetadataRequest
) -> Pin<Box<dyn Future<Output = Result<DomainMetadataResult, RusotoError<DomainMetadataError>>> + Send + 'async_trait>> where
'life0: 'async_trait,
Self: 'async_trait,
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.
sourcefn get_attributes<'life0, 'async_trait>(
&'life0 self,
input: GetAttributesRequest
) -> Pin<Box<dyn Future<Output = Result<GetAttributesResult, RusotoError<GetAttributesError>>> + Send + 'async_trait>> where
'life0: 'async_trait,
Self: 'async_trait,
fn get_attributes<'life0, 'async_trait>(
&'life0 self,
input: GetAttributesRequest
) -> Pin<Box<dyn Future<Output = Result<GetAttributesResult, RusotoError<GetAttributesError>>> + Send + 'async_trait>> where
'life0: 'async_trait,
Self: 'async_trait,
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.
sourcefn list_domains<'life0, 'async_trait>(
&'life0 self,
input: ListDomainsRequest
) -> Pin<Box<dyn Future<Output = Result<ListDomainsResult, RusotoError<ListDomainsError>>> + Send + 'async_trait>> where
'life0: 'async_trait,
Self: 'async_trait,
fn list_domains<'life0, 'async_trait>(
&'life0 self,
input: ListDomainsRequest
) -> Pin<Box<dyn Future<Output = Result<ListDomainsResult, RusotoError<ListDomainsError>>> + Send + 'async_trait>> where
'life0: 'async_trait,
Self: 'async_trait,
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.
sourcefn put_attributes<'life0, 'async_trait>(
&'life0 self,
input: PutAttributesRequest
) -> Pin<Box<dyn Future<Output = Result<(), RusotoError<PutAttributesError>>> + Send + 'async_trait>> where
'life0: 'async_trait,
Self: 'async_trait,
fn put_attributes<'life0, 'async_trait>(
&'life0 self,
input: PutAttributesRequest
) -> Pin<Box<dyn Future<Output = Result<(), RusotoError<PutAttributesError>>> + Send + 'async_trait>> where
'life0: 'async_trait,
Self: 'async_trait,
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
sourcefn select<'life0, 'async_trait>(
&'life0 self,
input: SelectRequest
) -> Pin<Box<dyn Future<Output = Result<SelectResult, RusotoError<SelectError>>> + Send + 'async_trait>> where
'life0: 'async_trait,
Self: 'async_trait,
fn select<'life0, 'async_trait>(
&'life0 self,
input: SelectRequest
) -> Pin<Box<dyn Future<Output = Result<SelectResult, RusotoError<SelectError>>> + Send + 'async_trait>> where
'life0: 'async_trait,
Self: 'async_trait,
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.
