Client for accessing AmazonSimpleDB. All service calls made using this client are blocking, and will not return until the service call completes.

Amazon SimpleDB

Amazon SimpleDB is a web service providing the core database functions of data indexing and querying in the cloud. By offloading the time and effort associated with building and operating a web-scale database, SimpleDB provides developers the freedom to focus on application development.

A traditional, clustered relational database requires a sizable upfront capital outlay, is complex to design, and often requires extensive and repetitive database administration. Amazon SimpleDB is dramatically simpler, requiring no schema, automatically indexing your data and providing a simple API for storage and access. This approach eliminates the administrative burden of data modeling, index maintenance, and performance tuning. Developers gain access to this functionality within Amazon's proven computing environment, are able to scale instantly, and pay only for what they use.

Visit http://aws.amazon.com/simpledb/ for more information.

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.

Parameters:
selectRequest Container for the necessary parameters to execute the Select service method on AmazonSimpleDB.
Returns:
The response from the Select service method, as returned by AmazonSimpleDB.
Throws:
com.amazonaws.services.simpledb.model.InvalidParameterValueException
com.amazonaws.services.simpledb.model.InvalidQueryExpressionException

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.

NOTE: Using PutAttributes to replace attribute values that do not exist will not result in an error response.

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

Parameters:
putAttributesRequest Container for the necessary parameters to execute the PutAttributes service method on AmazonSimpleDB.
Throws:
com.amazonaws.services.simpledb.model.InvalidParameterValueException
com.amazonaws.services.simpledb.model.NumberDomainBytesExceededException
com.amazonaws.services.simpledb.model.NumberDomainAttributesExceededException
com.amazonaws.services.simpledb.model.NoSuchDomainException
com.amazonaws.services.simpledb.model.NumberItemAttributesExceededException
com.amazonaws.services.simpledb.model.AttributeDoesNotExistException
com.amazonaws.services.simpledb.model.MissingParameterException
com.amazonaws.AmazonClientException If any internal errors are encountered inside the client while attempting to make the request or handle the response. For example if a network connection is not available.
com.amazonaws.AmazonServiceException If an error response is returned by AmazonSimpleDB indicating either a problem with the data in the request, or a server side issue.

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.

NOTE: If you specify BatchDeleteAttributes without attributes or values, all the attributes for the item are deleted. BatchDeleteAttributes is an idempotent operation; running it multiple times on the same item or attribute doesn't result in an error. The BatchDeleteAttributes operation succeeds or fails in its entirety. There are no partial deletes. You can execute multiple BatchDeleteAttributes operations and other operations in parallel. However, large numbers of concurrent BatchDeleteAttributes calls can result in Service Unavailable (503) responses. 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.

The following limitations are enforced for this operation:

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

Parameters:
batchDeleteAttributesRequest Container for the necessary parameters to execute the BatchDeleteAttributes service method on AmazonSimpleDB.
Throws:
com.amazonaws.AmazonClientException If any internal errors are encountered inside the client while attempting to make the request or handle the response. For example if a network connection is not available.
com.amazonaws.AmazonServiceException If an error response is returned by AmazonSimpleDB indicating either a problem with the data in the request, or a server side issue.
 
     public void batchDeleteAttributes(BatchDeleteAttributesRequest batchDeleteAttributesRequest) {
         ExecutionContext executionContext = createExecutionContext(batchDeleteAttributesRequest);

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.

NOTE: Running DeleteDomain on a domain that does not exist or running the function multiple times using the same domain name will not result in an error response.

Parameters:
deleteDomainRequest Container for the necessary parameters to execute the DeleteDomain service method on AmazonSimpleDB.
Throws:
com.amazonaws.services.simpledb.model.MissingParameterException
com.amazonaws.AmazonClientException If any internal errors are encountered inside the client while attempting to make the request or handle the response. For example if a network connection is not available.
com.amazonaws.AmazonServiceException If an error response is returned by AmazonSimpleDB indicating either a problem with the data in the request, or a server side issue.

             endClientExecution(awsRequestMetricsrequestnull);
         }
     }
    
    

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.

NOTE: CreateDomain is an idempotent operation; running it multiple times using the same domain name will not result in an error response.

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/ .

Parameters:
createDomainRequest Container for the necessary parameters to execute the CreateDomain service method on AmazonSimpleDB.
Throws:
com.amazonaws.services.simpledb.model.InvalidParameterValueException
com.amazonaws.services.simpledb.model.NumberDomainsExceededException
com.amazonaws.services.simpledb.model.MissingParameterException
com.amazonaws.AmazonClientException If any internal errors are encountered inside the client while attempting to make the request or handle the response. For example if a network connection is not available.
com.amazonaws.AmazonServiceException If an error response is returned by AmazonSimpleDB indicating either a problem with the data in the request, or a server side issue.

Deletes one or more attributes associated with an item. If all attributes of the item are deleted, the item is deleted.

NOTE: If DeleteAttributes is called without being passed any attributes or values specified, all the attributes for the item are 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.

Parameters:

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.

NOTE: If GetAttributes is called without being passed any attribute names, all the attributes for the item are returned.

Parameters:
getAttributesRequest Container for the necessary parameters to execute the GetAttributes service method on AmazonSimpleDB.
Returns:
The response from the GetAttributes service method, as returned by AmazonSimpleDB.
Throws:

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.

NOTE: You cannot specify an empty string as an item or as an attribute name. The BatchPutAttributes operation succeeds or fails in its entirety. There are no partial puts.

IMPORTANT: 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

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.

Parameters:
domainMetadataRequest Container for the necessary parameters to execute the DomainMetadata service method on AmazonSimpleDB.
Returns:
The response from the DomainMetadata service method, as returned by AmazonSimpleDB.
Throws:
com.amazonaws.services.simpledb.model.NoSuchDomainException
com.amazonaws.services.simpledb.model.MissingParameterException
com.amazonaws.AmazonClientException If any internal errors are encountered inside the client while attempting to make the request or handle the response. For example if a network connection is not available.
com.amazonaws.AmazonServiceException If an error response is returned by AmazonSimpleDB indicating either a problem with the data in the request, or a server side issue.

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.

Returns:
The response from the ListDomains service method, as returned by AmazonSimpleDB.
Throws:
com.amazonaws.services.simpledb.model.InvalidParameterValueException
com.amazonaws.services.simpledb.model.InvalidNextTokenException
com.amazonaws.AmazonClientException If any internal errors are encountered inside the client while attempting to make the request or handle the response. For example if a network connection is not available.
com.amazonaws.AmazonServiceException If an error response is returned by AmazonSimpleDB indicating either a problem with the data in the request, or a server side issue.
 
         return listDomains(new ListDomainsRequest());

Returns additional metadata for a previously executed successful, request, typically used for debugging issues where a service isn't acting as expected. This data isn't considered part of the result data returned by an operation, so it's available through this separate, diagnostic interface.

Response metadata is only cached for a limited period of time, so if you need to access this extra diagnostic information for an executed request, you should use this method to retrieve it as soon as possible after executing the request.

Parameters:
request The originally executed request
Returns:
The response metadata for the specified request, or null if none is available.
 
         ResponseMetadata metadata = .getResponseMetadataForRequest(request);
         if (metadata != null)
           return new SimpleDBResponseMetadata(metadata);
         else
           return null;
