// AddPermission API operation for Amazon Simple Queue Service.
//
// Adds a permission to a queue for a specific principal (http://docs.aws.amazon.com/general/latest/gr/glos-chap.html#P).
// 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 (http://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/acp-overview.html)
// in the Amazon SQS 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 (http://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/AccessPolicyLanguage.html)

// ChangeMessageVisibility API operation for Amazon Simple Queue Service.

// 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 (http://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/sqs-visibility-timeout.html)
// in the Amazon SQS Developer Guide.
//
// For example, you have a message and with the default 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.

// happens, repeat the request.
//
// For each message returned, the response includes the following:

// For more information, see Queue and Message Identifiers (http://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/sqs-queue-message-identifiers.html)
// in the Amazon SQS 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

// is used for the returned messages. For more information, see Visibility Timeout
// (http://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/sqs-visibility-timeout.html)
// in the Amazon SQS 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.
//

	// parameters that the CreateQueue action uses:
	//
	//    * DelaySeconds - The number of seconds for which the delivery of all messages
	//    in the queue is delayed. Valid values: An integer from 0 to 900 seconds
	//    (15 minutes). The default is 0 (zero).
	//
	//    * MaximumMessageSize - The limit of how many bytes a message can contain
	//    before Amazon SQS rejects it. Valid values: An integer from 1,024 bytes
	//    (1 KiB) to 262,144 bytes (256 KiB). The default is 262,144 (256 KiB).
	//
	//
	//    * MessageRetentionPeriod - The number of seconds for which Amazon SQS
	//    retains a message. Valid values: An integer from 60 seconds (1 minute)
	//    to 1,209,600 seconds (14 days). The default is 345,600 (4 days).
	//
	//    * Policy - The queue's policy. A valid AWS policy. For more information
	//    about policy structure, see Overview of AWS IAM Policies (http://docs.aws.amazon.com/IAM/latest/UserGuide/PoliciesOverview.html)
	//    in the Amazon IAM User Guide.
	//
	//    * ReceiveMessageWaitTimeSeconds - The number of seconds for which a ReceiveMessage
	//    action waits for a message to arrive. Valid values: An integer from 0
	//    to 20 (seconds). The default is 0 (zero).
	//
	//    * RedrivePolicy - The parameters for the dead letter queue functionality
	//    of the source queue. For more information about the redrive policy and
	//    dead letter queues, see Using Amazon SQS Dead Letter Queues (http://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/sqs-dead-letter-queues.html)
	//    in the Amazon SQS Developer Guide.
	//
	// The dead letter queue of a FIFO queue must also be a FIFO queue. Similarly,
	//    the dead letter queue of a standard queue must also be a standard queue.
	//
	//    * VisibilityTimeout - The visibility timeout for the queue. Valid values:
	//    An integer from 0 to 43,200 (12 hours). The default is 30. For more information
	//    about the visibility timeout, see Visibility Timeout (http://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/sqs-visibility-timeout.html)
	//    in the Amazon SQS Developer Guide.
	//
	// The following attributes apply only to FIFO (first-in-first-out) queues (http://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/FIFO-queues.html):
	//
	//    * FifoQueue - Designates a queue as FIFO. You can provide this attribute
	//    only during queue creation. You can't change it for an existing queue.
	//    When you set this attribute, you must provide a MessageGroupId explicitly.
	//
	// For more information, see FIFO Queue Logic (http://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/FIFO-queues.html#FIFO-queues-understanding-logic)
	//    in the Amazon SQS Developer Guide.
	//
	//    * ContentBasedDeduplication - Enables content-based deduplication. For
	//    more information, see Exactly-Once Processing (http://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/FIFO-queues.html#FIFO-queues-exactly-once-processing)
	//    in the Amazon SQS Developer Guide.
	//
	// Every message must have a unique MessageDeduplicationId,
	//
	// You may provide a MessageDeduplicationId explicitly.
	//
	// If you aren't able to provide a MessageDeduplicationId and you enable ContentBasedDeduplication
	//    for your queue, Amazon SQS uses a SHA-256 hash to generate the MessageDeduplicationId
	//    using the body of the message (but not the attributes of the message).
	//
	//
	// If you don't provide a MessageDeduplicationId and the queue doesn't have
	//    ContentBasedDeduplication set, the action fails with an error.
	//
	// If the queue has ContentBasedDeduplication set, your MessageDeduplicationId
	//    overrides the generated one.
	//
	// When ContentBasedDeduplication is in effect, messages with identical content
	//    sent within the deduplication interval are treated as duplicates and only
	//    one copy of the message is delivered.
	//
	// You can also use ContentBasedDeduplication for messages with identical content
	//    to be treated as duplicates.
	//
	// If you send one message with ContentBasedDeduplication enabled and then another
	//    message with a MessageDeduplicationId that is the same as the one generated
	//    for the first MessageDeduplicationId, the two messages are treated as
	//    duplicates and only one copy of the message is delivered.

	// To mitigate this effect, ensure that your application observes a safe threshold

	//    timeout expires. You can still receive messages with another MessageGroupId
	//    as long as it is also visible.
	//
	//    * If a caller of ReceiveMessage can't track the ReceiveRequestAttemptId,

	_ struct{} `type:"structure"`

	// A map of attributes to set.
	//
	// The following lists the names, descriptions, and values of the special request
	// parameters that the SetQueueAttributes action uses:
	//
	//    * DelaySeconds - The number of seconds for which the delivery of all messages
	//    in the queue is delayed. Valid values: An integer from 0 to 900 (15 minutes).
	//    The default is 0 (zero).
	//
	//    * MaximumMessageSize - The limit of how many bytes a message can contain
	//    before Amazon SQS rejects it. Valid values: An integer from 1,024 bytes
	//    (1 KiB) up to 262,144 bytes (256 KiB). The default is 262,144 (256 KiB).
	//
	//
	//    * MessageRetentionPeriod - The number of seconds for which Amazon SQS
	//    retains a message. Valid values: An integer representing seconds, from
	//    60 (1 minute) to 1,209,600 (14 days). The default is 345,600 (4 days).
	//
	//
	//    * Policy - The queue's policy. A valid AWS policy. For more information
	//    about policy structure, see Overview of AWS IAM Policies (http://docs.aws.amazon.com/IAM/latest/UserGuide/PoliciesOverview.html)
	//    in the Amazon IAM User Guide.
	//
	//    * ReceiveMessageWaitTimeSeconds - The number of seconds for which a ReceiveMessage
	//    action waits for a message to arrive. Valid values: an integer from 0
	//    to 20 (seconds). The default is 0.
	//
	//    * RedrivePolicy - The parameters for the dead letter queue functionality
	//    of the source queue. For more information about the redrive policy and
	//    dead letter queues, see Using Amazon SQS Dead Letter Queues (http://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/sqs-dead-letter-queues.html)
	//    in the Amazon SQS Developer Guide.
	//
	// The dead letter queue of a FIFO queue must also be a FIFO queue. Similarly,
	//    the dead letter queue of a standard queue must also be a standard queue.
	//
	//    * VisibilityTimeout - The visibility timeout for the queue. Valid values:
	//    an integer from 0 to 43,200 (12 hours). The default is 30. For more information
	//    about the visibility timeout, see Visibility Timeout (http://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/sqs-visibility-timeout.html)
	//    in the Amazon SQS Developer Guide.
	//
	// The following attribute applies only to FIFO (first-in-first-out) queues
	// (http://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/FIFO-queues.html):
	//
	//    * ContentBasedDeduplication - Enables content-based deduplication. For
	//    more information, see Exactly-Once Processing (http://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/FIFO-queues.html#FIFO-queues-exactly-once-processing)
	//    in the Amazon SQS Developer Guide.
	//
	// Every message must have a unique MessageDeduplicationId,
	//
	// You may provide a MessageDeduplicationId explicitly.
	//
	// If you aren't able to provide a MessageDeduplicationId and you enable ContentBasedDeduplication
	//    for your queue, Amazon SQS uses a SHA-256 hash to generate the MessageDeduplicationId
	//    using the body of the message (but not the attributes of the message).
	//
	//
	// If you don't provide a MessageDeduplicationId and the queue doesn't have
	//    ContentBasedDeduplication set, the action fails with an error.
	//
	// If the queue has ContentBasedDeduplication set, your MessageDeduplicationId
	//    overrides the generated one.
	//
	// When ContentBasedDeduplication is in effect, messages with identical content
	//    sent within the deduplication interval are treated as duplicates and only
	//    one copy of the message is delivered.
	//
	// You can also use ContentBasedDeduplication for messages with identical content
	//    to be treated as duplicates.
	//
	// If you send one message with ContentBasedDeduplication enabled and then another
	//    message with a MessageDeduplicationId that is the same as the one generated
	//    for the first MessageDeduplicationId, the two messages are treated as
	//    duplicates and only one copy of the message is delivered.
	//
