@Generated(value="com.amazonaws:aws-java-sdk-code-generator") public interface AmazonSQSAsync extends AmazonSQS
AsyncHandler
can be used to receive
notification when an asynchronous operation completes.
Note: Do not directly implement this interface, new methods are added to it regularly. Extend from
AbstractAmazonSQSAsync
instead.
Welcome to the Amazon Simple Queue Service API Reference.
Amazon Simple Queue Service (Amazon SQS) is a reliable, highly-scalable hosted queue for storing messages as they travel between applications or microservices. Amazon SQS moves data between distributed application components and helps you decouple these components.
Standard queues are available in all regions. FIFO queues are available in the US East (N. Virginia), US East (Ohio), US West (Oregon), and EU (Ireland) regions.
You can use AWS SDKs to access Amazon SQS using your favorite programming language. The SDKs perform tasks such as the following automatically:
Cryptographically sign your service requests
Retry requests
Handle error responses

Future<AddPermissionResult> addPermissionAsync(AddPermissionRequest addPermissionRequest)
Adds a permission to a queue for a specific principal. This allows sharing access to the queue.
When you create a queue, you have full control access rights for the queue. Only you, the owner of the queue, can grant or deny permissions to the queue. For more information about these permissions, see Shared Queues in the Amazon Simple Queue Service Developer Guide.
AddPermission
writes an Amazon-SQS-generated policy. If you want to write your own policy, use
SetQueueAttributes
to upload your policy. For more information about writing your own
policy, see Using
The Access Policy Language in the Amazon Simple Queue Service Developer Guide.
Some actions take lists of parameters. These lists are specified using the param.n
notation. Values
of n
are integers starting from 1. For example, a parameter list with two elements looks like this:
&Attribute.1=this
&Attribute.2=that

- Asynchronous callback handler for events in the lifecycle of the request. Users can provide an

Future<ChangeMessageVisibilityResult> changeMessageVisibilityAsync(ChangeMessageVisibilityRequest changeMessageVisibilityRequest)
Changes the visibility timeout of a specified message in a queue to a new value. The maximum allowed timeout value is 12 hours. Thus, you can't extend the timeout of a message in an existing queue to more than a total visibility timeout of 12 hours. For more information, see Visibility Timeout in the Amazon Simple Queue Service Developer Guide.
For example, you have a message with a visibility timeout of 5 minutes. After 3 minutes, you call
ChangeMessageVisiblity
with a timeout of 10 minutes. At that time, the timeout for the message is
extended by 10 minutes beyond the time of the ChangeMessageVisibility
action. This results in a
total visibility timeout of 13 minutes. You can continue to call the ChangeMessageVisibility
to
extend the visibility timeout to a maximum of 12 hours. If you try to extend the visibility timeout beyond 12
hours, your request is rejected.
A message is considered to be in flight after it's received from a queue by a consumer, but not yet deleted from the queue.
For standard queues, there can be a maximum of 120,000 inflight messages per queue. If you reach this limit,
Amazon SQS returns the OverLimit
error message. To avoid reaching the limit, you should delete
messages from the queue after they're processed. You can also increase the number of queues you use to process
your messages.
For FIFO queues, there can be a maximum of 20,000 inflight messages per queue. If you reach this limit, Amazon SQS returns no error messages.
If you attempt to set the VisibilityTimeout
to a value greater than the maximum time left, Amazon
SQS returns an error. Amazon SQS doesn't automatically recalculate and increase the timeout to the maximum
remaining time.
Unlike with a queue, when you change the visibility timeout for a specific message the timeout value is applied
immediately but isn't saved in memory for that message. If you don't delete a message after it is received, the
visibility timeout for the message reverts to the original timeout value (not to the value you set using the
ChangeMessageVisibility
action) the next time the message is received.

Future<ChangeMessageVisibilityBatchResult> changeMessageVisibilityBatchAsync(ChangeMessageVisibilityBatchRequest changeMessageVisibilityBatchRequest)
Changes the visibility timeout of multiple messages. This is a batch version of
ChangeMessageVisibility.
The result of the action on each message is reported individually
in the response. You can send up to 10 ChangeMessageVisibility
requests with each
ChangeMessageVisibilityBatch
action.
Because the batch request can result in a combination of successful and unsuccessful actions, you should check
for batch errors even when the call returns an HTTP status code of 200
.
Some actions take lists of parameters. These lists are specified using the param.n
notation. Values

Future<CreateQueueResult> createQueueAsync(CreateQueueRequest createQueueRequest)
Creates a new standard or FIFO queue. You can pass one or more attributes in the request. Keep the following caveats in mind:
If you don't specify the FifoQueue
attribute, Amazon SQS creates a standard queue.
You can't change the queue type after you create it and you can't convert an existing standard queue into a FIFO queue. You must either create a new FIFO queue for your application or delete your existing standard queue and recreate it as a FIFO queue. For more information, see Moving From a Standard Queue to a FIFO Queue in the Amazon Simple Queue Service Developer Guide.
If you don't provide a value for an attribute, the queue is created with the default value for the attribute.
If you delete a queue, you must wait at least 60 seconds before creating a queue with the same name.
To successfully create a new queue, you must provide a queue name that adheres to the limits related to queues and is unique within the scope of your queues.
To get the queue URL, use the GetQueueUrl
action. GetQueueUrl
requires only the QueueName
parameter. be aware of existing queue names:
If you provide the name of an existing queue along with the exact names and values of all the queue's attributes,
CreateQueue
returns the queue URL for the existing queue.
If the queue name, attribute names, or attribute values don't match an existing queue, CreateQueue
returns an error.

Future<CreateQueueResult> createQueueAsync(String queueName, AsyncHandler<CreateQueueRequest,CreateQueueResult> asyncHandler)
Future<DeleteMessageResult> deleteMessageAsync(DeleteMessageRequest deleteMessageRequest)
Deletes the specified message from the specified queue. You specify the message by using the message's receipt handle and not the MessageId you receive when you send the message. Even if the message is locked by another reader due to the visibility timeout setting, it is still deleted from the queue. If you leave a message in the queue for longer than the queue's configured retention period, Amazon SQS automatically deletes the message.
The receipt handle is associated with a specific instance of receiving the message. If you receive a message more
than once, the receipt handle you get each time you receive the message is different. If you don't provide the
most recently received receipt handle for the message when you use the DeleteMessage
action, the
request succeeds, but the message might not be deleted.
For standard queues, it is possible to receive a message even after you delete it. This might happen on rare occasions if one of the servers storing a copy of the message is unavailable when you send the request to delete the message. The copy remains on the server and might be returned to you on a subsequent receive request. You should ensure that your application is idempotent, so that receiving a message more than once does not cause issues.

than once, the receipt handle you get each time you receive the message is different. If you don't provide the
most recently received receipt handle for the message when you use the DeleteMessage
action, the
request succeeds, but the message might not be deleted.
For standard queues, it is possible to receive a message even after you delete it. This might happen on rare occasions if one of the servers storing a copy of the message is unavailable when you send the request to delete the message. The copy remains on the server and might be returned to you on a subsequent receive request. You should ensure that your application is idempotent, so that receiving a message more than once does not cause issues.

Deletes up to ten messages from the specified queue. This is a batch version of
DeleteMessage.
The result of the action on each message is reported individually in the
response.
Because the batch request can result in a combination of successful and unsuccessful actions, you should check
for batch errors even when the call returns an HTTP status code of 200
.
Some actions take lists of parameters. These lists are specified using the param.n
notation. Values
of n
are integers starting from 1. For example, a parameter list with two elements looks like this:

Be careful with the DeleteQueue
action: When you delete a queue, any messages in the queue are no
longer available.
When you delete a queue, the deletion process takes up to 60 seconds. Requests you send involving that queue
during the 60 seconds might succeed. For example, a SendMessage
request might succeed, but
after 60 seconds the queue and the message you sent no longer exist.
When you delete a queue, you must wait at least 60 seconds before creating a queue with the same name.

Retrieves one or more messages (up to 10), from the specified queue. Using the WaitTimeSeconds
parameter enables long-poll support. For more information, see Amazon SQS
Long Polling in the Amazon Simple Queue Service Developer Guide.
Short poll is the default behavior where a weighted random set of machines is sampled on a
ReceiveMessage
call. Thus, only the messages on the sampled machines are returned. If the number of
messages in the queue is small (fewer than 1,000), you most likely get fewer messages than you requested per
ReceiveMessage
call. If the number of messages in the queue is extremely small, you might not
receive any messages in a particular ReceiveMessage
response. If this happens, repeat the request.
For each message returned, the response includes the following:
The message body.
An MD5 digest of the message body. For information about MD5, see RFC1321.
The MessageId
you received when you sent the message to the queue.
The receipt handle.
The message attributes.
An MD5 digest of the message attributes.
The receipt handle is the identifier you must provide when deleting the message. For more information, see Queue and Message Identifiers in the Amazon Simple Queue Service Developer Guide.
You can provide the VisibilityTimeout
parameter in your request. The parameter is applied to the
messages that Amazon SQS returns in the response. If you don't include the parameter, the overall visibility
timeout for the queue is used for the returned messages. For more information, see Visibility Timeout in the Amazon Simple Queue Service Developer Guide.
A message that isn't deleted or a message whose visibility isn't extended before the visibility timeout expires counts as a failed receive. Depending on the configuration of the queue, the message might be sent to the dead-letter queue.
In the future, new attributes might be added. If you write code that calls this action, we recommend that you structure your code so that it can handle new attributes gracefully.
