batchDeleteAttributesAsync
public Future<BatchDeleteAttributesResult> batchDeleteAttributesAsync(BatchDeleteAttributesRequest request) Description copied from interface:AmazonSimpleDBAsync
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
- Specified by:
batchDeleteAttributesAsync
in interfaceAmazonSimpleDBAsync
- Parameters:
request
-- Returns:
- A Java Future containing the result of the BatchDeleteAttributes operation returned by the service.

batchDeleteAttributesAsync
public Future<BatchDeleteAttributesResult> batchDeleteAttributesAsync(BatchDeleteAttributesRequest request, AsyncHandler<BatchDeleteAttributesRequest, BatchDeleteAttributesResult> asyncHandler) Description copied from interface:AmazonSimpleDBAsync
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
- Specified by:
batchDeleteAttributesAsync
in interfaceAmazonSimpleDBAsync
- Parameters:
request
-asyncHandler
- Asynchronous callback handler for events in the lifecycle of the request. Users can provide an implementation of the callback methods in this interface to receive notification of successful or unsuccessful completion of the operation.- Returns:
- A Java Future containing the result of the BatchDeleteAttributes operation returned by the service.
-
batchPutAttributesAsync
Description copied from interface:AmazonSimpleDBAsync
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 theItem.X.Attribute.Y.Name
andItem.X.Attribute.Y.Value
parameters. The client may specify the first attribute for the first item using the parametersItem.0.Attribute.0.Name
andItem.0.Attribute.0.Value
, and for the second attribute for the first item by the parametersItem.0.Attribute.1.Name
andItem.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 theItem.X.Attribute.Y.Name
andItem.X.Attribute.Y.Value
are the same.Optionally, the requester can supply the
Replace
parameter for each individual value. Setting this value totrue
will cause the new attribute values to replace the existing attribute values. For example, if an itemI
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
, orExpected.X.Exists
.You can execute multiple
BatchPutAttributes
operations and other operations in parallel. However, large numbers of concurrentBatchPutAttributes
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
- Specified by:
batchPutAttributesAsync
in interfaceAmazonSimpleDBAsync
- Parameters:
request
-- Returns:
- A Java Future containing the result of the BatchPutAttributes operation returned by the service.

deleteAttributesAsync
Description copied from interface:AmazonSimpleDBAsync
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.- Specified by:
deleteAttributesAsync
in interfaceAmazonSimpleDBAsync
- Parameters:
request
-- Returns:
- A Java Future containing the result of the DeleteAttributes operation returned by the service.
-

putAttributesAsync
Description copied from interface:AmazonSimpleDBAsync
The PutAttributes operation creates or replaces attributes in an item. The client may specify new attributes using a combination of the
Attribute.X.Name
andAttribute.X.Value
parameters. The client specifies the first attribute by the parametersAttribute.0.Name
andAttribute.0.Value
, the second attribute by the parametersAttribute.1.Name
andAttribute.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 theAttribute.X.Name
andAttribute.X.Value
are the same.Optionally, the requestor can supply the
Replace
parameter for each individual attribute. Setting this value totrue
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 callsPutAttributes
using the attributes{ 'b', '4' }
with theReplace
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
- Specified by:
putAttributesAsync
in interfaceAmazonSimpleDBAsync
- Parameters:
request
-- Returns:
- A Java Future containing the result of the PutAttributes operation returned by the service.

selectAsync
Description copied from interface:AmazonSimpleDBAsync
The
Select
operation returns a set of attributes forItemNames
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.
