public interface AmazonSimpleDB
Interface for accessing AmazonSimpleDB. 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.

|---|
void setEndpoint(String endpoint)
throws IllegalArgumentException
Callers can pass in just the endpoint (ex: "sdb.amazonaws.com") or a full
URL, including the protocol (ex: "http://sdb.amazonaws.com"). If the
protocol is not specified here, the default protocol from this client's
ClientConfiguration will be used, which by default is HTTPS.
For more information on using AWS regions with the AWS SDK for Java, and a complete list of all available endpoints for all AWS services, see: http://developer.amazonwebservices.com/connect/entry.jspa?externalID=3912
endpoint - The endpoint (ex: "sdb.amazonaws.com") or a full URL,
including the protocol (ex: "http://sdb.amazonaws.com") of
the region specific AWS endpoint this client will communicate
with.
IllegalArgumentException - If any problems are detected with the specified endpoint.
SelectResult select(SelectRequest selectRequest)
throws AmazonServiceException,
AmazonClientException
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.
selectRequest - Container for the necessary parameters to execute
the Select service method on AmazonSimpleDB.
InvalidParameterValueException
InvalidQueryExpressionException
RequestTimeoutException
InvalidNumberPredicatesException
NoSuchDomainException
InvalidNextTokenException
TooManyRequestedAttributesException
MissingParameterException
InvalidNumberValueTestsException
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.
AmazonServiceException - If an error response is returned by AmazonSimpleDB indicating
either a problem with the data in the request, or a server side issue.
void putAttributes(PutAttributesRequest putAttributesRequest)
throws AmazonServiceException,
AmazonClientException
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:
putAttributesRequest - Container for the necessary parameters to
execute the PutAttributes service method on AmazonSimpleDB.
InvalidParameterValueException
NumberDomainBytesExceededException
NumberDomainAttributesExceededException
NoSuchDomainException
NumberItemAttributesExceededException
AttributeDoesNotExistException
MissingParameterException
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.
AmazonServiceException - If an error response is returned by AmazonSimpleDB indicating
either a problem with the data in the request, or a server side issue.
void batchDeleteAttributes(BatchDeleteAttributesRequest batchDeleteAttributesRequest)
throws AmazonServiceException,
AmazonClientException
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:
batchDeleteAttributesRequest - Container for the necessary
parameters to execute the BatchDeleteAttributes service method on
AmazonSimpleDB.
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.
AmazonServiceException - If an error response is returned by AmazonSimpleDB indicating
either a problem with the data in the request, or a server side issue.
void deleteDomain(DeleteDomainRequest deleteDomainRequest)
throws AmazonServiceException,
AmazonClientException
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.
deleteDomainRequest - Container for the necessary parameters to
execute the DeleteDomain service method on AmazonSimpleDB.
MissingParameterException
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.
AmazonServiceException - If an error response is returned by AmazonSimpleDB indicating
either a problem with the data in the request, or a server side issue.
void createDomain(CreateDomainRequest createDomainRequest)
throws AmazonServiceException,
AmazonClientException
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/ .
createDomainRequest - Container for the necessary parameters to
execute the CreateDomain service method on AmazonSimpleDB.
InvalidParameterValueException
NumberDomainsExceededException
MissingParameterException
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.
AmazonServiceException - If an error response is returned by AmazonSimpleDB indicating
either a problem with the data in the request, or a server side issue.
void deleteAttributes(DeleteAttributesRequest deleteAttributesRequest)
throws AmazonServiceException,
AmazonClientException
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.
deleteAttributesRequest - Container for the necessary parameters
to execute the DeleteAttributes service method on AmazonSimpleDB.
InvalidParameterValueException
NoSuchDomainException
AttributeDoesNotExistException
MissingParameterException
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.
AmazonServiceException - If an error response is returned by AmazonSimpleDB indicating
either a problem with the data in the request, or a server side issue.
ListDomainsResult listDomains(ListDomainsRequest listDomainsRequest)
throws AmazonServiceException,
AmazonClientException
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.
listDomainsRequest - Container for the necessary parameters to
execute the ListDomains service method on AmazonSimpleDB.
InvalidParameterValueException
InvalidNextTokenException
AmazonClientException - If any internal errors are encountered inside the client while
attempting to make the request or handle the response. For example

AmazonServiceException - If an error response is returned by AmazonSimpleDB indicating
either a problem with the data in the request, or a server side issue.
GetAttributesResult getAttributes(GetAttributesRequest getAttributesRequest)
throws AmazonServiceException,
AmazonClientException
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.
getAttributesRequest - Container for the necessary parameters to
execute the GetAttributes service method on AmazonSimpleDB.
InvalidParameterValueException
NoSuchDomainException
MissingParameterException
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.
AmazonServiceException - If an error response is returned by AmazonSimpleDB indicating
either a problem with the data in the request, or a server side issue.
void batchPutAttributes(BatchPutAttributesRequest batchPutAttributesRequest)
throws AmazonServiceException,
AmazonClientException
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:
