@ThreadSafe public class AmazonSimpleDBAsyncClient extends AmazonSimpleDBClient implements AmazonSimpleDBAsync
AsyncHandler can be used to
receive notification when an asynchronous operation completes.
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.

public Future<BatchDeleteAttributesResult> batchDeleteAttributesAsync(BatchDeleteAttributesRequest request)
AmazonSimpleDBAsyncPerforms 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:

The following limitations are enforced for this operation:
batchDeleteAttributesAsync in interface AmazonSimpleDBAsyncasyncHandler - 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.public Future<BatchPutAttributesResult> batchPutAttributesAsync(BatchPutAttributesRequest request)
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 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.

AmazonSimpleDBAsync
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.

AmazonSimpleDBAsyncDeletes 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.

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

{ "first_name", "first_value" } and

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.

AmazonSimpleDBAsync
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.
