BatchDeleteAttributes

DomainName => Str

Items => ArrayRef[Paws::SDB::DeletableItem]

Each argument is described in detail in: Paws::SDB::BatchDeleteAttributes

Returns: nothing

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

BatchPutAttributes

DomainName => Str

Items => ArrayRef[Paws::SDB::ReplaceableItem]

Each argument is described in detail in: Paws::SDB::BatchPutAttributes

Returns: nothing

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

CreateDomain

DomainName => Str

Each argument is described in detail in: Paws::SDB::CreateDomain

Returns: nothing

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/ (http://aws.amazon.com/contact-us/simpledb-limit-request/).

DeleteAttributes

DomainName => Str

ItemName => Str

[Attributes => ArrayRef[Paws::SDB::DeletableAttribute]]

[Expected => Paws::SDB::UpdateCondition]

Each argument is described in detail in: Paws::SDB::DeleteAttributes

Returns: nothing

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.

DeleteDomain

DomainName => Str

Each argument is described in detail in: Paws::SDB::DeleteDomain

Returns: nothing

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.

DomainMetadata

DomainName => Str

Each argument is described in detail in: Paws::SDB::DomainMetadata

Returns: a Paws::SDB::DomainMetadataResult instance

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.

GetAttributes

DomainName => Str

ItemName => Str

[AttributeName => Str]

[ConsistentRead => Bool]

Each argument is described in detail in: Paws::SDB::GetAttributes

Returns: a Paws::SDB::GetAttributesResult instance

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.

ListDomains

[MaxNumberOfDomains => Int]

[NextToken => Str]

Each argument is described in detail in: Paws::SDB::ListDomains

Returns: a Paws::SDB::ListDomainsResult instance

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.

PutAttributes

Attributes => ArrayRef[Paws::SDB::ReplaceableAttribute]

DomainName => Str

ItemName => Str

[Expected => Paws::SDB::UpdateCondition]

Each argument is described in detail in: Paws::SDB::PutAttributes

Returns: nothing

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

Select

SelectExpression => Str

[ConsistentRead => Bool]

[NextToken => Str]

Each argument is described in detail in: Paws::SDB::Select

Returns: a Paws::SDB::SelectResult instance

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.

ListAllDomains(sub { },[MaxNumberOfDomains => Int, NextToken => Str])

ListAllDomains([MaxNumberOfDomains => Int, NextToken => Str])

If passed a sub as first parameter, it will call the sub for each element found in :

 - DomainNames, passing the object as the first parameter, and the string 'DomainNames' as the second parameter

If not, it will return a a Paws::SDB::ListDomainsResult instance with all the "param"s; from all the responses. Please take into account that this mode can potentially consume vasts ammounts of memory.

SelectAll(sub { },SelectExpression => Str, [ConsistentRead => Bool, NextToken => Str])

SelectAll(SelectExpression => Str, [ConsistentRead => Bool, NextToken => Str])

If passed a sub as first parameter, it will call the sub for each element found in :

 - Items, passing the object as the first parameter, and the string 'Items' as the second parameter

If not, it will return a a Paws::SDB::SelectResult instance with all the "param"s; from all the responses. Please take into account that this mode can potentially consume vasts ammounts of memory.
