All Implemented Interfaces:
com.amazonaws.services.sqs.AmazonSQS

public class AmazonSQSExtendedClient extends Object implements com.amazonaws.services.sqs.AmazonSQS
Amazon SQS Extended Client extends the functionality of Amazon SQS client. All service calls made using this client are blocking, and will not return until the service call completes.

The Amazon SQS extended client enables sending and receiving large messages via Amazon S3. You can use this library to:

  • Specify whether messages are always stored in Amazon S3 or only when a message size exceeds 256 KB.
  • Send a message that references a single message object stored in an Amazon S3 bucket.
  • Get the corresponding message object from an Amazon S3 bucket.
  • Delete the corresponding message object from an Amazon S3 bucket.

    • receiveMessage

      public com.amazonaws.services.sqs.model.ReceiveMessageResult receiveMessage(com.amazonaws.services.sqs.model.ReceiveMessageRequest receiveMessageRequest)

      Retrieves one or more messages, with a maximum limit of 10 messages, from the specified queue. Downloads the message payloads from Amazon S3 when necessary. 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 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; 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 .

      NOTE: 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:
      receiveMessage in interface com.amazonaws.services.sqs.AmazonSQS
      Parameters:
      receiveMessageRequest - Container for the necessary parameters to execute the ReceiveMessage service method on AmazonSQS.
      Returns:
      The response from the ReceiveMessage service method, as returned by AmazonSQS.
      Throws:
      com.amazonaws.services.sqs.model.OverLimitException
      com.amazonaws.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.
      com.amazonaws.AmazonServiceException - If an error response is returned by AmazonSQS indicating either a problem with the data in the request, or a server side issue.
    • receiveMessage

      public com.amazonaws.services.sqs.model.ReceiveMessageResult receiveMessage(String queueUrl)

      Retrieves one or more messages, with a maximum limit of 10 messages, from the specified queue. Downloads the message payloads from Amazon S3 when necessary. Long poll support is enabled by using the WaitTimeSeconds parameter. For more information, see Amazon SQS Long Poll in the Amazon SQS Developer Guide .

      • 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 .

      NOTE: 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:
      receiveMessage in interface com.amazonaws.services.sqs.AmazonSQS
      Parameters:
      queueUrl - The URL of the Amazon SQS queue to take action on.
      Returns:
      The response from the ReceiveMessage service method, as returned by AmazonSQS.
      Throws:
      com.amazonaws.services.sqs.model.OverLimitException
      com.amazonaws.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.
      com.amazonaws.AmazonServiceException - If an error response is returned by AmazonSQS indicating either a problem with the data in the request, or a server side issue.
    • deleteMessage

      public com.amazonaws.services.sqs.model.DeleteMessageResult deleteMessage(com.amazonaws.services.sqs.model.DeleteMessageRequest deleteMessageRequest)

      Deletes the specified message from the specified queue and deletes the message payload from Amazon S3 when necessary. You specify the message by using the message's receipt handle and not the message 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.

      NOTE: 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.

      IMPORTANT: 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 interface com.amazonaws.services.sqs.AmazonSQS
      Parameters:
      deleteMessageRequest - Container for the necessary parameters to execute the DeleteMessage service method on AmazonSQS.
      Returns:
      The response from the DeleteMessage service method, as returned by AmazonSQS.
      Throws:
      com.amazonaws.services.sqs.model.ReceiptHandleIsInvalidException
      com.amazonaws.services.sqs.model.InvalidIdFormatException
      com.amazonaws.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.
      com.amazonaws.AmazonServiceException - If an error response is returned by AmazonSQS indicating either a problem with the data in the request, or a server side issue.
    • deleteMessage

      public com.amazonaws.services.sqs.model.DeleteMessageResult deleteMessage(String queueUrl, String receiptHandle)

    • changeMessageVisibility

      public com.amazonaws.services.sqs.model.ChangeMessageVisibilityResult changeMessageVisibility(String queueUrl, String receiptHandle, Integer visibilityTimeout)
      Simplified method form for invoking the ChangeMessageVisibility operation.
      Specified by:
      changeMessageVisibility in interface com.amazonaws.services.sqs.AmazonSQS
      Parameters:
      queueUrl - The URL of the Amazon SQS queue to take action on.
      receiptHandle - The receipt handle associated with the message whose visibility timeout should be changed. This parameter is returned by the ReceiveMessage action.
      visibilityTimeout - The new value (in seconds - from 0 to 43200 - maximum 12 hours) for the message's visibility timeout.
      Returns:
      The response from the ChangeMessageVisibility service method, as returned by AmazonSQS.

    • changeMessageVisibility

      public com.amazonaws.services.sqs.model.ChangeMessageVisibilityResult changeMessageVisibility(com.amazonaws.services.sqs.model.ChangeMessageVisibilityRequest changeMessageVisibilityRequest) throws com.amazonaws.AmazonServiceException, com.amazonaws.AmazonClientException

      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 30 minutes. You could call ChangeMessageVisiblity with a value of two hours and the effective timeout would be two hours and 30 minutes. When that time comes near you could again extend the time out by calling ChangeMessageVisiblity, but this time the maximum allowed timeout would be 9 hours and 30 minutes.

      NOTE: 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.

      IMPORTANT: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.

      IMPORTANT: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 interface com.amazonaws.services.sqs.AmazonSQS
      Parameters:
      changeMessageVisibilityRequest - Container for the necessary parameters to execute the ChangeMessageVisibility service method on AmazonSQS.
      Throws:
      com.amazonaws.services.sqs.model.ReceiptHandleIsInvalidException
      com.amazonaws.services.sqs.model.MessageNotInflightException
      com.amazonaws.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.

      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.

      NOTE: 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. Permitted attributes are the same that can be set using SetQueueAttributes.

      NOTE: 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.

      NOTE:Some API 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:

      NOTE: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.

      NOTE:Some API 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

      Specified by:
      getQueueAttributes in interface com.amazonaws.services.sqs.AmazonSQS
      Parameters:
      queueUrl - The URL of the Amazon SQS queue to take action on.

    • deleteQueue

      public com.amazonaws.services.sqs.model.DeleteQueueResult deleteQueue(String queueUrl) throws com.amazonaws.AmazonServiceException, com.amazonaws.AmazonClientException

      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.

      IMPORTANT: 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 .

      Specified by:
      deleteQueue in interface com.amazonaws.services.sqs.AmazonSQS
      Parameters:
      queueUrl - The URL of the Amazon SQS queue to take action on.
      Returns:
      The response from the DeleteQueue service method, as returned by AmazonSQS.

    • listQueues

      public com.amazonaws.services.sqs.model.ListQueuesResult listQueues(String queueNamePrefix) throws com.amazonaws.AmazonServiceException, com.amazonaws.AmazonClientException

      Returns a list of your queues. The maximum number of queues that can be returned is 1000. If you specify a value for the optional QueueNamePrefix parameter, only queues with a name beginning with the specified value are returned.

      Specified by:
      listQueues in interface com.amazonaws.services.sqs.AmazonSQS
      Parameters:
      queueNamePrefix - A string to use for filtering the list results. Only those queues whose name begins with the specified string are returned.
      Returns:
      The response from the ListQueues service method, as returned by AmazonSQS.
      Throws:
      com.amazonaws.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.

    • createQueue

      public com.amazonaws.services.sqs.model.CreateQueueResult createQueue(String queueName) throws com.amazonaws.AmazonServiceException, com.amazonaws.AmazonClientException

      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.

      NOTE: 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. Permitted attributes are the same that can be set using SetQueueAttributes.

      NOTE: 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.

      NOTE:Some API 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

      Specified by:
      createQueue in interface com.amazonaws.services.sqs.AmazonSQS
      Parameters:

    • addPermission

      public com.amazonaws.services.sqs.model.AddPermissionResult addPermission(String queueUrl, String label, List<String> aWSAccountIds, List<String> actions) throws com.amazonaws.AmazonServiceException, com.amazonaws.AmazonClientException

      Adds a permission to a queue for a specific principal . This allows for sharing access to the queue.

      When you create a queue, you have full control access rights for the queue. Only you (as owner of the queue) can grant or deny permissions to the queue. For more information about these permissions, see Shared Queues in the Amazon SQS Developer Guide .

      NOTE: 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 SQS Developer Guide.

      NOTE:Some API 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

      Specified by:
      addPermission in interface com.amazonaws.services.sqs.AmazonSQS
      Parameters:
      queueUrl - The URL of the Amazon SQS queue to take action on.
      label - The unique identification of the permission you're setting (e.g., AliceSendMessage). Constraints: Maximum 80 characters; alphanumeric characters, hyphens (-), and underscores (_) are allowed.
      aWSAccountIds - The AWS account number of the principal who will be given permission. The principal must have an AWS account, but does not need to be signed up for Amazon SQS. For information about locating the AWS account identification, see Your AWS Identifiers in the Amazon SQS Developer Guide.
      actions - The action the client wants to allow for the specified principal. The following are valid values: * | SendMessage | ReceiveMessage | DeleteMessage | ChangeMessageVisibility | GetQueueAttributes | GetQueueUrl. For more information about these actions, see Understanding Permissions in the Amazon SQS Developer Guide.

      Specifying SendMessage, DeleteMessage, or ChangeMessageVisibility for the ActionName.n also grants permissions for the corresponding batch versions of those actions: SendMessageBatch, DeleteMessageBatch , and ChangeMessageVisibilityBatch.

      Returns:
      The response from the AddPermission service method, as returned by AmazonSQS.
      Throws:
      com.amazonaws.services.sqs.model.OverLimitException
      com.amazonaws.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.
      com.amazonaws.AmazonServiceException - If an error response is returned by AmazonSQS indicating either a problem with the data in the request, or a server side issue.
    • getCachedResponseMetadata

      public com.amazonaws.ResponseMetadata getCachedResponseMetadata(com.amazonaws.AmazonWebServiceRequest request)
      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 the request.

      Specified by:
      getCachedResponseMetadata in interface com.amazonaws.services.sqs.AmazonSQS
      Parameters:
      request - The originally executed request
      Returns:
      The response metadata for the specified request, or null if none is available.
    • setEndpoint

      public void setEndpoint(String endpoint) throws IllegalArgumentException
      Overrides the default endpoint for this client ("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: "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 interface com.amazonaws.services.sqs.AmazonSQS
      Parameters:
      endpoint - The endpoint (ex: "sqs.us-east-1.amazonaws.com") or a full URL, including the protocol (ex: "sqs.us-east-1.amazonaws.com") of the region specific AWS endpoint this client will communicate with.
      Throws:
      IllegalArgumentException - If any problems are detected with the specified endpoint.
    • setRegion

      public void setRegion(com.amazonaws.regions.Region region) throws IllegalArgumentException
      An alternative to AmazonSQS.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 interface com.amazonaws.services.sqs.AmazonSQS
      Parameters:
      region - The region this client will communicate with. See Region.getRegion(com.amazonaws.regions.Regions) for accessing a given region.
      Throws:
      IllegalArgumentException - If the given region is null, or if this service isn't available in the given region. See Region.isServiceSupported(String)
      See Also:
      • Region.getRegion(com.amazonaws.regions.Regions)
      • Region.createClient(Class, AWSCredentialsProvider, ClientConfiguration)
    • shutdown

      public void shutdown()
      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.
