Class AmazonSQSBufferedAsyncClient
- All Implemented Interfaces:
AmazonSQS
,AmazonSQSAsync
After receiving a call, rather than executing it right away, this client waits for a configurable period of time ( default=200ms) for other calls of the same type to come in; if such calls do come in, they are also not executed immediately, but instead are added to the batch. When the batch becomes full or the timeout period expires, the entire batch is executed at once and the results are returned to the callers. This method of operation leads to reduced operating costs (since SQS charges per call and fewer calls are made) and increased overall throughput (since more work is performed per call, and all fixed costs of making a call are amortized over a greater amount of work). The cost of this method is increased latency for individual calls, since calls spend some time waiting on the client side for the potential batch-mates to appear before they are actually executed.
This client also performs pre-fetching of messages from SQS. After the first receiveMessage call is made, the client attempts not only to satisfy that call, but also pre-fetch extra messages to store in a temporary buffer. Future receiveMessage calls will be satisfied from the buffer, and only if the buffer is empty will the calling thread have to wait for the messages to be fetched. The size of the buffer and the maximum number of threads used for prefetching are configurable.
AmazonSQSBufferedAsyncClient is thread-safe.

setRegion
Description copied from interface:AmazonSQS
An alternative toAmazonSQS.setEndpoint(String)
, sets the regional endpoint for this client's service calls. Callers can use this method to control which AWS region they want to work with.By default, all service endpoints in all regions use the https protocol. To use http instead, specify it in the
ClientConfiguration
supplied at construction.This method is not threadsafe. A region should be configured when the client is created and before any service requests are made. Changing it afterwards creates inevitable race conditions for any service requests in transit or retrying.
- Specified by:
setRegion
in interfaceAmazonSQS
- Parameters:
region
- The region this client will communicate with. SeeRegion.getRegion(com.amazonaws.regions.Regions)
for accessing a given region. Must not be null and must be a region where the service is available.- Throws:
IllegalArgumentException

setQueueAttributes
public SetQueueAttributesResult setQueueAttributes(SetQueueAttributesRequest setQueueAttributesRequest) throws AmazonServiceException, AmazonClientException Description copied from interface:AmazonSQS
Sets the value of one or more queue attributes. When you change a queue's attributes, the change can take up to 60 seconds for most of the attributes to propagate throughout the SQS system. Changes made to the
MessageRetentionPeriod
attribute can take up to 15 minutes.Going forward, new attributes might be added. If you are writing code that calls this action, we recommend that you structure your code so that it can handle new attributes gracefully.
- Specified by:
setQueueAttributes
in interfaceAmazonSQS
- Parameters:
setQueueAttributesRequest
-- Returns:
- Result of the SetQueueAttributes operation returned by the service.
- Throws:
AmazonServiceException
AmazonClientException
-
changeMessageVisibilityBatch
public ChangeMessageVisibilityBatchResult changeMessageVisibilityBatch(ChangeMessageVisibilityBatchRequest changeMessageVisibilityBatchRequest) throws AmazonServiceException, AmazonClientException Description copied from interface:AmazonSQS
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 API actions take lists of parameters. These lists are specified using the
param.n
notation. Values ofn
are integers starting from 1. For example, a parameter list with two elements looks like this:- Specified by:
changeMessageVisibilityBatch
in interfaceAmazonSQS
- Parameters:
changeMessageVisibilityBatchRequest
-- Returns:
- Result of the ChangeMessageVisibilityBatch operation returned by the service.
- Throws:
AmazonServiceException
AmazonClientException
-
changeMessageVisibility
public ChangeMessageVisibilityResult changeMessageVisibility(ChangeMessageVisibilityRequest changeMessageVisibilityRequest) throws AmazonServiceException, AmazonClientException Description copied from interface:AmazonSQS
Changes the visibility timeout of a specified message in a queue to a new value. The maximum allowed timeout value you can set the value to is 12 hours. This means 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 visibility timeout, see Visibility Timeout in the Amazon SQS Developer Guide.)
For example, let's say you have a message and its default message visibility timeout is 5 minutes. After 3 minutes, you call
ChangeMessageVisiblity
with a timeout of 10 minutes. At that time, the timeout for the message would be extended by 10 minutes beyond the time of the ChangeMessageVisibility call. This results in a total visibility timeout of 13 minutes. You can continue to call ChangeMessageVisibility to extend the visibility timeout to a maximum of 12 hours. If you try to extend beyond 12 hours, the request will be rejected.There is a 120,000 limit for the number of inflight messages per queue. Messages are inflight after they have been received from the queue by a consuming component, but have not yet been deleted from the queue. If you reach the 120,000 limit, you will receive an OverLimit error message from Amazon SQS. To help avoid reaching the limit, you should delete the messages from the queue after they have been processed. You can also increase the number of queues you use to process the messages.
If you attempt to set the
VisibilityTimeout
to an amount more than the maximum time left, Amazon SQS returns an error. It will not automatically recalculate and increase the timeout to the maximum time remaining.Unlike with a queue, when you change the visibility timeout for a specific message, that timeout value is applied immediately but is not saved in memory for that message. If you don't delete a message after it is received, the visibility timeout for the message the next time it is received reverts to the original timeout value, not the value you set with the
ChangeMessageVisibility
action.- Specified by:
changeMessageVisibility
in interfaceAmazonSQS
- Parameters:
changeMessageVisibilityRequest
-- Returns:
- Result of the ChangeMessageVisibility operation returned by the service.
- Throws:
AmazonServiceException
AmazonClientException
-
sendMessageBatch
public SendMessageBatchResult sendMessageBatch(SendMessageBatchRequest sendMessageBatchRequest) throws AmazonServiceException, AmazonClientException Description copied from interface:AmazonSQS
Delivers up to ten messages to the specified queue. This is a batch version of SendMessage. The result of the send action on each message is reported individually in the response. The maximum allowed individual message size is 256 KB (262,144 bytes).
The maximum total payload size (i.e., the sum of all a batch's individual message lengths) is also 256 KB (262,144 bytes).
If the
DelaySeconds
parameter is not specified for an entry, the default for the queue is used.The following list shows the characters (in Unicode) that are allowed in your message, according to the W3C XML specification. For more information, go to http:// www.faqs.org/rfcs/rfc1321.html. If you send any characters that are not included in the list, your request will be rejected.
#x9 | #xA | #xD | [#x20 to #xD7FF] | [#xE000 to #xFFFD] | [#x10000 to #x10FFFF]
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 API actions take lists of parameters. These lists are specified using the
param.n
notation. Values ofn
are integers starting from 1. For example, a parameter list with two elements looks like this:- Specified by:
sendMessageBatch
in interfaceAmazonSQS
- Parameters:
sendMessageBatchRequest
-- Returns:
- Result of the SendMessageBatch operation returned by the service.
- Throws:
AmazonServiceException
AmazonClientException
-
sendMessage
public SendMessageResult sendMessage(SendMessageRequest sendMessageRequest) throws AmazonServiceException, AmazonClientException Description copied from interface:AmazonSQS
Delivers a message to the specified queue. With Amazon SQS, you now have the ability to send large payload messages that are up to 256KB (262,144 bytes) in size. To send large payloads, you must use an AWS SDK that supports SigV4 signing. To verify whether SigV4 is supported for an AWS SDK, check the SDK release notes.
The following list shows the characters (in Unicode) allowed in your message, according to the W3C XML specification. For more information, go to http://www.w3.org/TR/REC -xml/#charsets If you send any characters not included in the list, your request will be rejected.
#x9 | #xA | #xD | [#x20 to #xD7FF] | [#xE000 to #xFFFD] | [#x10000 to #x10FFFF]

- Throws:
AmazonServiceException
AmazonClientException
-
receiveMessage
public ReceiveMessageResult receiveMessage(ReceiveMessageRequest receiveMessageRequest) throws AmazonServiceException, AmazonClientException Description copied from interface:AmazonSQS
Retrieves one or more messages, with a maximum limit of 10 messages, from the specified queue. Long poll support is enabled by using the
WaitTimeSeconds
parameter. For more information, see Amazon SQS Long Poll in the Amazon SQS Developer Guide.Short poll is the default behavior where a weighted random set of machines is sampled on a
ReceiveMessage
call. This means only the messages on the sampled machines are returned. If the number of messages in the queue is small (less than 1000), it is likely you will get fewer messages than you requested perReceiveMessage
call. If the number of messages in the queue is extremely small, you might not receive any messages in a particularReceiveMessage
response; in which case you should repeat the request.For each message returned, the response includes the following:
-
Message body
-
MD5 digest of the message body. For information about MD5, go to http://www.faqs.org/rfcs/rfc1321.html.
-
Message ID you received when you sent the message to the queue.
-
Receipt handle.
-
Message attributes.
-
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 SQS Developer Guide.
You can provide the
VisibilityTimeout
parameter in your request, which will be applied to the messages that Amazon SQS returns in the response. If you do not 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 SQS Developer Guide.Going forward, new attributes might be added. If you are writing code that calls this action, we recommend that you structure your code so that it can handle new attributes gracefully.

deleteMessageBatch
public DeleteMessageBatchResult deleteMessageBatch(DeleteMessageBatchRequest deleteMessageBatchRequest) throws AmazonServiceException, AmazonClientException Description copied from interface:AmazonSQS
Deletes up to ten messages from the specified queue. This is a batch version of DeleteMessage. The result of the delete 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 API actions take lists of parameters. These lists are specified using the
param.n
notation. Values ofn
are integers starting from 1. For example, a parameter list with two elements looks like this:- Specified by:

- Throws:
AmazonServiceException
AmazonClientException
-
deleteMessage
public DeleteMessageResult deleteMessage(DeleteMessageRequest deleteMessageRequest) throws AmazonServiceException, AmazonClientException Description copied from interface:AmazonSQS
Deletes the specified message from the specified queue. You specify the message by using the message's
receipt handle
and not themessage ID
you received when you sent 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 it.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. When you request
DeleteMessage
, if you don't provide the most recently received receipt handle for the message, the request will still succeed, but the message might not be deleted.It is possible you will receive a message even after you have deleted it. This might happen on rare occasions if one of the servers storing a copy of the message is unavailable when you request to delete the message. The copy remains on the server and might be returned to you again on a subsequent receive request. You should create your system to be idempotent so that receiving a particular message more than once is not a problem.
- Specified by:
deleteMessage
in interfaceAmazonSQS
- Parameters:
deleteMessageRequest
-- Returns:
- Result of the DeleteMessage operation returned by the service.
- Throws:

shutdown
public void shutdown()Description copied from interface:AmazonSQS
Shuts down this client object, releasing any resources that might be held open. This is an optional method, and callers are not expected to call it, but can if they want to explicitly release any open resources. Once a client has been shutdown, it should not be used to make any more requests. -
changeMessageVisibilityBatchAsync
public Future<ChangeMessageVisibilityBatchResult> changeMessageVisibilityBatchAsync(ChangeMessageVisibilityBatchRequest changeMessageVisibilityBatchRequest) throws AmazonServiceException, AmazonClientException Description copied from interface:AmazonSQSAsync
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.

Delivers a message to the specified queue. With Amazon SQS, you now have the ability to send large payload messages that are up to 256KB (262,144 bytes) in size. To send large payloads, you must use an AWS SDK that supports SigV4 signing. To verify whether SigV4 is supported for an AWS SDK, check the SDK release notes.
The following list shows the characters (in Unicode) allowed in your message, according to the W3C XML specification. For more information, go to http://www.w3.org/TR/REC -xml/#charsets If you send any characters not included in the list, your request will be rejected.
#x9 | #xA | #xD | [#x20 to #xD7FF] | [#xE000 to #xFFFD] | [#x10000 to #x10FFFF]
- Specified by:

- Parameters:
sendMessageRequest
-- Returns:
- A Java Future containing the result of the SendMessage operation returned by the service.
- Throws:
AmazonServiceException
AmazonClientException
-
receiveMessageAsync
public Future<ReceiveMessageResult> receiveMessageAsync(ReceiveMessageRequest receiveMessageRequest) throws AmazonServiceException, AmazonClientException Description copied from interface:AmazonSQSAsync
Retrieves one or more messages, with a maximum limit of 10 messages, from the specified queue. Long poll support is enabled by using the
WaitTimeSeconds
parameter. For more information, see Amazon SQS Long Poll in the Amazon SQS Developer Guide.Short poll is the default behavior where a weighted random set of machines is sampled on a
ReceiveMessage
call. This means only the messages on the sampled machines are returned. If the number of messages in the queue is small (less than 1000), it is likely you will get fewer messages than you requested perReceiveMessage
call. If the number of messages in the queue is extremely small, you might not receive any messages in a particularReceiveMessage
response; in which case you should repeat the request.For each message returned, the response includes the following:
-
Message body
-
MD5 digest of the message body. For information about MD5, go to http://www.faqs.org/rfcs/rfc1321.html.
-
Message ID you received when you sent the message to the queue.
-
Receipt handle.
-
Message attributes.
-
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 SQS Developer Guide.
You can provide the
VisibilityTimeout
parameter in your request, which will be applied to the messages that Amazon SQS returns in the response. If you do not 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 SQS Developer Guide.Going forward, new attributes might be added. If you are writing code that calls this action, we recommend that you structure your code so that it can handle new attributes gracefully.

deleteMessageBatchAsync
public Future<DeleteMessageBatchResult> deleteMessageBatchAsync(DeleteMessageBatchRequest deleteMessageBatchRequest) throws AmazonServiceException, AmazonClientException Description copied from interface:AmazonSQSAsync
Deletes up to ten messages from the specified queue. This is a batch version of DeleteMessage. The result of the delete 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 API actions take lists of parameters. These lists are specified using the
param.n
notation. Values ofn
are integers starting from 1. For example, a parameter list with two elements looks like this:- Specified by:
deleteMessageBatchAsync
in interfaceAmazonSQSAsync
- Parameters:
deleteMessageBatchRequest

-
setEndpoint
Description copied from interface:AmazonSQS
Overrides the default endpoint for this client ("https://sqs.us-east-1.amazonaws.com"). Callers can use this method to control which AWS region they want to work with.Callers can pass in just the endpoint (ex: "sqs.us-east-1.amazonaws.com") or a full URL, including the protocol (ex: "https://sqs.us-east-1.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
This method is not threadsafe. An endpoint should be configured when the client is created and before any service requests are made. Changing it afterwards creates inevitable race conditions for any service requests in transit or retrying.
- Specified by:
setEndpoint
in interfaceAmazonSQS
- Parameters:
endpoint
- The endpoint (ex: "sqs.us-east-1.amazonaws.com") or a full URL, including the protocol (ex: "https://sqs.us-east-1.amazonaws.com") of the region specific AWS endpoint this client will communicate with.- Throws:

getCachedResponseMetadata
Description copied from interface:AmazonSQS
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 a request.
- Specified by:
getCachedResponseMetadata

- Parameters:
request
- The originally executed request.- Returns:
- The response metadata for the specified request, or null if none is available.
-
deleteMessageAsync
public Future<DeleteMessageResult> deleteMessageAsync(DeleteMessageRequest deleteMessageRequest) throws AmazonServiceException, AmazonClientException Description copied from interface:AmazonSQSAsync
Deletes the specified message from the specified queue. You specify the message by using the message's
receipt handle
and not themessage ID
you received when you sent 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 it.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. When you request
DeleteMessage
, if you don't provide the most recently received receipt handle for the message, the request will still succeed, but the message might not be deleted.It is possible you will receive a message even after you have deleted it. This might happen on rare occasions if one of the servers storing a copy of the message is unavailable when you request to delete the message. The copy remains on the server and might be returned to you again on a subsequent receive request. You should create your system to be idempotent so that receiving a particular message more than once is not a problem.
- Specified by:

-
changeMessageVisibilityAsync
public Future<ChangeMessageVisibilityResult> changeMessageVisibilityAsync(ChangeMessageVisibilityRequest changeMessageVisibilityRequest, AsyncHandler<ChangeMessageVisibilityRequest, ChangeMessageVisibilityResult> asyncHandler) throws AmazonServiceException, AmazonClientExceptionDescription copied from interface:AmazonSQSAsync
Changes the visibility timeout of a specified message in a queue to a new value. The maximum allowed timeout value you can set the value to is 12 hours. This means 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 visibility timeout, see Visibility Timeout in the Amazon SQS Developer Guide.)
For example, let's say you have a message and its default message visibility timeout is 5 minutes. After 3 minutes, you call
ChangeMessageVisiblity
with a timeout of 10 minutes. At that time, the timeout for the message would be extended by 10 minutes beyond the time of the ChangeMessageVisibility call. This results in a total visibility timeout of 13 minutes. You can continue to call ChangeMessageVisibility to extend the visibility timeout to a maximum of 12 hours. If you try to extend beyond 12 hours, the request will be rejected.There is a 120,000 limit for the number of inflight messages per queue. Messages are inflight after they have been received from the queue by a consuming component, but have not yet been deleted from the queue. If you reach the 120,000 limit, you will receive an OverLimit error message from Amazon SQS. To help avoid reaching the limit, you should delete the messages from the queue after they have been processed. You can also increase the number of queues you use to process the messages.
If you attempt to set the
VisibilityTimeout
to an amount more than the maximum time left, Amazon SQS returns an error. It will not automatically recalculate and increase the timeout to the maximum time remaining.Unlike with a queue, when you change the visibility timeout for a specific message, that timeout value is applied immediately but is not saved in memory for that message. If you don't delete a message after it is received, the visibility timeout for the message the next time it is received reverts to the original timeout value, not the value you set with the
ChangeMessageVisibility
action.- Specified by:
changeMessageVisibilityAsync

Retrieves one or more messages, with a maximum limit of 10 messages, from the specified queue. Long poll support is enabled by using the
WaitTimeSeconds
parameter. For more information, see Amazon SQS Long Poll in the Amazon SQS Developer Guide.Short poll is the default behavior where a weighted random set of machines is sampled on a
ReceiveMessage

call. If the number of messages in the queue is extremely small, you might not receive any messages in a particularReceiveMessage
response; in which case you should repeat the request.For each message returned, the response includes the following:
-
Message body
-
MD5 digest of the message body. For information about MD5, go to http://www.faqs.org/rfcs/rfc1321.html.
-
Message ID you received when you sent the message to the queue.
-
Receipt handle.
-
Message attributes.
-
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 SQS Developer Guide.
You can provide the
VisibilityTimeout
parameter in your request, which will be applied to the messages that Amazon SQS returns in the response. If you do not 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 SQS Developer Guide.Going forward, new attributes might be added. If you are writing code that calls this action, we recommend that you structure your code so that it can handle new attributes gracefully.

public Future<DeleteMessageResult> deleteMessageAsync(DeleteMessageRequest deleteMessageRequest, AsyncHandler<DeleteMessageRequest, DeleteMessageResult> asyncHandler) throws AmazonServiceException, AmazonClientExceptionDescription copied from interface:AmazonSQSAsync
Deletes the specified message from the specified queue. You specify the message by using the message's
receipt handle
and not themessage ID
you received when you sent 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 it.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. When you request
DeleteMessage
, if you don't provide the most recently received receipt handle for the message, the request will still succeed, but the message might not be deleted.It is possible you will receive a message even after you have deleted it. This might happen on rare occasions if one of the servers storing a copy of the message is unavailable when you request to delete the message. The copy remains on the server and might be returned to you again on a subsequent receive request. You should create your system to be idempotent so that receiving a particular message more than once is not a problem.

public Future<PurgeQueueResult> purgeQueueAsync(PurgeQueueRequest purgeQueueRequest, AsyncHandler<PurgeQueueRequest, PurgeQueueResult> asyncHandler) throws AmazonServiceException, AmazonClientExceptionDescription copied from interface:AmazonSQSAsync
Deletes the messages in a queue specified by the queue URL.
When you use the
PurgeQueue
API, the deleted messages in the queue cannot be retrieved.When you purge a queue, the message deletion process takes up to 60 seconds. All messages sent to the queue before calling
PurgeQueue
will be deleted; messages sent to the queue while it is being purged may be deleted. While the queue is being purged, messages sent to the queue beforePurgeQueue
was called may be received, but will be deleted within the next minute.- Specified by:
purgeQueueAsync

deleteQueueAsync
public Future<DeleteQueueResult> deleteQueueAsync(DeleteQueueRequest deleteQueueRequest, AsyncHandler<DeleteQueueRequest, DeleteQueueResult> asyncHandler) throws AmazonServiceException, AmazonClientExceptionDescription copied from interface:AmazonSQSAsync
Deletes the queue specified by the queue URL, regardless of whether the queue is empty. If the specified queue does not exist, Amazon SQS returns a successful response.
Use
DeleteQueue
with care; once you delete your 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 the 60 seconds, the queue and that message you sent no longer exist. Also, when you delete a queue, you must wait at least 60 seconds before creating a queue with the same name.
We reserve the right to delete queues that have had no activity for more than 30 days. For more information, see How Amazon SQS Queues Work in the Amazon SQS Developer Guide.

Creates a new queue, or returns the URL of an existing one. When you request
CreateQueue
, you provide a name for the queue. To successfully create a new queue, you must provide a name that is unique within the scope of your own queues.If you delete a queue, you must wait at least 60 seconds before creating a queue with the same name.
You may pass one or more attributes in the request. If you do not provide a value for any attribute, the queue will have the default value for that attribute.
Use GetQueueUrl to get a queue's URL. GetQueueUrl requires only the
QueueName
parameter.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 do not match an existing queue,CreateQueue
returns an error.Some API actions take lists of parameters. These lists are specified using the
