    add_permission(awsaccount_id, action_name, label, queue_url)
    add_permission(awsaccount_id, action_name, label, queue_url, params::Dict{String,<:Any})

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 Allow Developers to Write Messages to a Shared
Queue in the Amazon Simple Queue Service Developer Guide.     AddPermission generates a
policy for you. You can use  SetQueueAttributes  to upload your policy. For more
information, see Using Custom Policies with the Amazon SQS Access Policy Language in the
Amazon Simple Queue Service Developer Guide.   An Amazon SQS policy can have a maximum of 7
actions.   To remove the ability to change queue permissions, you must deny permission to
the AddPermission, RemovePermission, and SetQueueAttributes actions in your IAM policy.
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:  &AttributeName.1=first   &AttributeName.2=second
Cross-account permissions don't apply to this action. For more information, see Grant
cross-account permissions to a role and a user name in the Amazon Simple Queue Service
Developer Guide.

# Arguments
- `awsaccount_id`: The AWS account number of the principal who is 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 Simple Queue Service Developer Guide.
- `action_name`: The action the client wants to allow for the specified principal. Valid
  values: the name of any action or *. For more information about these actions, see Overview
  of Managing Access Permissions to Your Amazon Simple Queue Service Resource in the Amazon
  Simple Queue Service Developer Guide. Specifying SendMessage, DeleteMessage, or
  ChangeMessageVisibility for ActionName.n also grants permissions for the corresponding
  batch versions of those actions: SendMessageBatch, DeleteMessageBatch, and
  ChangeMessageVisibilityBatch.
- `label`: The unique identification of the permission you're setting (for example,
  AliceSendMessage). Maximum 80 characters. Allowed characters include alphanumeric
  characters, hyphens (-), and underscores (_).
- `queue_url`: The URL of the Amazon SQS queue to which permissions are added. Queue URLs
  and names are case-sensitive.

# Optional Parameters
Optional parameters can be passed as a `params::Dict{String,<:Any}`. Valid keys are:
- `"AWSAccountIds"`: The AWS account number of the principal who is 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 Simple Queue Service Developer Guide.
- `"Actions"`: The action the client wants to allow for the specified principal. Valid
  values: the name of any action or *. For more information about these actions, see Overview
  of Managing Access Permissions to Your Amazon Simple Queue Service Resource in the Amazon
  Simple Queue Service Developer Guide. Specifying SendMessage, DeleteMessage, or
  ChangeMessageVisibility for ActionName.n also grants permissions for the corresponding

    change_message_visibility(queue_url, receipt_handle, visibility_timeout)
    change_message_visibility(queue_url, receipt_handle, visibility_timeout, params::Dict{String,<:Any})

Changes the visibility timeout of a specified message in a queue to a new value. The
default visibility timeout for a message is 30 seconds. The minimum is 0 seconds. The
maximum is 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 ChangeMessageVisibility with a timeout of 10 minutes.
You can continue to call ChangeMessageVisibility to extend the visibility timeout to the
maximum allowed time. If you try to extend the visibility timeout beyond the maximum, your
request is rejected. An Amazon SQS message has three basic states:   Sent to a queue by a
producer.   Received from the queue by a consumer.   Deleted from the queue.   A message is
considered to be stored after it is sent to a queue by a producer, but not yet received
from the queue by a consumer (that is, between states 1 and 2). There is no limit to the
number of stored messages. A message is considered to be in flight after it is received
from a queue by a consumer, but not yet deleted from the queue (that is, between states 2
and 3). There is a limit to the number of inflight messages. Limits that apply to inflight
messages are unrelated to the unlimited number of stored messages. For most standard queues
(depending on queue traffic and message backlog), there can be a maximum of approximately
120,000 inflight messages (received from a queue by a consumer, but not yet deleted from
the 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. To
request a limit increase, file a support request. For FIFO queues, there can be a maximum
of 20,000 inflight messages (received from a queue by a consumer, but not yet deleted from
the 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.

# Arguments
- `queue_url`: The URL of the Amazon SQS queue whose message's visibility is changed. Queue
  URLs and names are case-sensitive.
- `receipt_handle`: The receipt handle associated with the message whose visibility timeout
  is changed. This parameter is returned by the  ReceiveMessage  action.
- `visibility_timeout`: The new value for the message's visibility timeout (in seconds).
  Values range: 0 to 43200. Maximum: 12 hours.

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

    create_queue(queue_name)
    create_queue(queue_name, params::Dict{String,<:Any})

Creates a new standard or FIFO queue. You can pass one or more attributes in the request.
Keep the following 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.  After you create a queue,
you must wait at least one second after the queue is created to be able to use the queue.
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.
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:  &AttributeName.1=first   &AttributeName.2=second
Cross-account permissions don't apply to this action. For more information, see Grant
cross-account permissions to a role and a user name in the Amazon Simple Queue Service
Developer Guide.

# Arguments
- `queue_name`: The name of the new queue. The following limits apply to this name:   A
  queue name can have up to 80 characters.   Valid values: alphanumeric characters, hyphens
  (-), and underscores (_).   A FIFO queue name must end with the .fifo suffix.   Queue URLs
  and names are case-sensitive.

# Optional Parameters
Optional parameters can be passed as a `params::Dict{String,<:Any}`. Valid keys are:
- `"Attribute"`: A map of attributes with their corresponding values. The following lists
  the names, descriptions, and values of the special request parameters that the CreateQueue
  action uses:    DelaySeconds – The length of time, in seconds, for which the delivery of
  all messages in the queue is delayed. Valid values: An integer from 0 to 900 seconds (15
  minutes). Default: 0.     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). Default: 262,144 (256 KiB).     MessageRetentionPeriod – The
  length of time, in seconds, for which Amazon SQS retains a message. Valid values: An
  integer from 60 seconds (1 minute) to 1,209,600 seconds (14 days). Default: 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 in the Amazon IAM User Guide.
  ReceiveMessageWaitTimeSeconds – The length of time, in seconds, for which a
  ReceiveMessage  action waits for a message to arrive. Valid values: An integer from 0 to 20
  (seconds). Default: 0.     RedrivePolicy – The string that includes the parameters for
  the dead-letter queue functionality of the source queue as a JSON object. For more
  information about the redrive policy and dead-letter queues, see Using Amazon SQS
  Dead-Letter Queues in the Amazon Simple Queue Service Developer Guide.
  deadLetterTargetArn – The Amazon Resource Name (ARN) of the dead-letter queue to which
  Amazon SQS moves messages after the value of maxReceiveCount is exceeded.
  maxReceiveCount – The number of times a message is delivered to the source queue before
  being moved to the dead-letter queue. When the ReceiveCount for a message exceeds the
  maxReceiveCount for a queue, Amazon SQS moves the message to the dead-letter-queue.    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, in seconds. Valid values: An integer from 0 to 43,200 (12
  hours). Default: 30. For more information about the visibility timeout, see Visibility
  Timeout in the Amazon Simple Queue Service Developer Guide.   The following attributes
  apply only to server-side-encryption:    KmsMasterKeyId – The ID of an AWS-managed
  customer master key (CMK) for Amazon SQS or a custom CMK. For more information, see Key
  Terms. While the alias of the AWS-managed CMK for Amazon SQS is always alias/aws/sqs, the
  alias of a custom CMK can, for example, be alias/MyAlias . For more examples, see KeyId in
  the AWS Key Management Service API Reference.     KmsDataKeyReusePeriodSeconds – The
  length of time, in seconds, for which Amazon SQS can reuse a data key to encrypt or decrypt
  messages before calling AWS KMS again. An integer representing seconds, between 60 seconds
  (1 minute) and 86,400 seconds (24 hours). Default: 300 (5 minutes). A shorter time period
  provides better security but results in more calls to KMS which might incur charges after
  Free Tier. For more information, see How Does the Data Key Reuse Period Work?.    The
  following attributes apply only to FIFO (first-in-first-out) queues:    FifoQueue –
  Designates a queue as FIFO. Valid values are true and false. If you don't specify the
  FifoQueue attribute, Amazon SQS creates a standard queue. 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 also provide the MessageGroupId for your messages explicitly. For more
  information, see FIFO Queue Logic in the Amazon Simple Queue Service Developer Guide.
  ContentBasedDeduplication – Enables content-based deduplication. Valid values are true
  and false. For more information, see Exactly-Once Processing in the Amazon Simple Queue
  Service Developer Guide. Note the following:    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.   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.       Preview: High throughput for FIFO queues   High throughput for
  Amazon SQS FIFO queues is in preview release and is subject to change. This feature
  provides a high number of transactions per second (TPS) for messages in FIFO queues. For
  information on throughput quotas, see Quotas related to messages in the Amazon Simple Queue
  Service Developer Guide. This preview includes two new attributes:    DeduplicationScope
  – Specifies whether message deduplication occurs at the message group or queue level.
  Valid values are messageGroup and queue.    FifoThroughputLimit – Specifies whether the
  FIFO queue throughput quota applies to the entire queue or per message group. Valid values
  are perQueue and perMessageGroupId. The perMessageGroupId value is allowed only when the
  value for DeduplicationScope is messageGroup.   To enable high throughput for FIFO queues,
  do the following:   Set DeduplicationScope to messageGroup.   Set FifoThroughputLimit to
  perMessageGroupId.   If you set these attributes to anything other than the values shown
  for enabling high throughput, standard throughput is in effect and deduplication occurs as
  specified. This preview is available in the following AWS Regions:   US East (Ohio);
  us-east-2   US East (N. Virginia); us-east-1   US West (Oregon); us-west-2   Europe
  (Ireland); eu-west-1   For more information about high throughput for FIFO queues, see
  Preview: High throughput for FIFO queues in the Amazon Simple Queue Service Developer Guide.
- `"Tag"`: Add cost allocation tags to the specified Amazon SQS queue. For an overview, see
  Tagging Your Amazon SQS Queues in the Amazon Simple Queue Service Developer Guide. When you
  use queue tags, keep the following guidelines in mind:   Adding more than 50 tags to a
  queue isn't recommended.   Tags don't have any semantic meaning. Amazon SQS interprets tags
  as character strings.   Tags are case-sensitive.   A new tag with a key identical to that
  of an existing tag overwrites the existing tag.   For a full list of tag restrictions, see
  Limits Related to Queues in the Amazon Simple Queue Service Developer Guide.  To be able to
  tag a queue on creation, you must have the sqs:CreateQueue and sqs:TagQueue permissions.
  Cross-account permissions don't apply to this action. For more information, see Grant
  cross-account permissions to a role and a user name in the Amazon Simple Queue Service
  Developer Guide.

    delete_message(queue_url, receipt_handle)
    delete_message(queue_url, receipt_handle, params::Dict{String,<:Any})

Deletes the specified message from the specified queue. To select the message to delete,
use the ReceiptHandle of the message (not the MessageId which you receive when you send the
message). Amazon SQS can delete a message from a queue even if a visibility timeout setting
causes the message to be locked by another consumer. Amazon SQS automatically deletes
messages left in a queue longer than the retention period configured for the queue.   The
ReceiptHandle is associated with a specific instance of receiving a message. If you receive
a message more than once, the ReceiptHandle is different each time you receive a message.
When you use the DeleteMessage action, you must provide the most recently received
ReceiptHandle for the message (otherwise, 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 which stores 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 during a subsequent receive request. You should
ensure that your application is idempotent, so that receiving a message more than once does
not cause issues.

"""
    receive_message(queue_url)
    receive_message(queue_url, params::Dict{String,<:Any})

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.

# Arguments
- `queue_url`: The URL of the Amazon SQS queue from which messages are received. Queue URLs
  and names are case-sensitive.

# Optional Parameters
Optional parameters can be passed as a `params::Dict{String,<:Any}`. Valid keys are:
- `"AttributeNames"`: A list of attributes that need to be returned along with each
  message. These attributes include:    All – Returns all values.
  ApproximateFirstReceiveTimestamp – Returns the time the message was first received from
  the queue (epoch time in milliseconds).    ApproximateReceiveCount – Returns the number
  of times a message has been received across all queues but not deleted.    AWSTraceHeader
  – Returns the AWS X-Ray trace header string.     SenderId    For an IAM user, returns the
  IAM user ID, for example ABCDEFGHI1JKLMNOPQ23R.   For an IAM role, returns the IAM role ID,
  for example ABCDE1F2GH3I4JK5LMNOP:i-a123b456.      SentTimestamp – Returns the time the
  message was sent to the queue (epoch time in milliseconds).    MessageDeduplicationId –
  Returns the value provided by the producer that calls the  SendMessage  action.
  MessageGroupId – Returns the value provided by the producer that calls the  SendMessage
  action. Messages with the same MessageGroupId are returned in sequence.    SequenceNumber
  – Returns the value provided by Amazon SQS.
- `"MaxNumberOfMessages"`: The maximum number of messages to return. Amazon SQS never
  returns more messages than this value (however, fewer messages might be returned). Valid
  values: 1 to 10. Default: 1.
- `"MessageAttributeNames"`: The name of the message attribute, where N is the index.   The
  name can contain alphanumeric characters and the underscore (_), hyphen (-), and period
  (.).   The name is case-sensitive and must be unique among all attribute names for the
  message.   The name must not start with AWS-reserved prefixes such as AWS. or Amazon. (or
  any casing variants).   The name must not start or end with a period (.), and it should not
  have periods in succession (..).   The name can be up to 256 characters long.   When using
  ReceiveMessage, you can send a list of attribute names to receive, or you can return all of
  the attributes by specifying All or .* in your request. You can also use all message
  attributes starting with a prefix, for example bar.*.
- `"ReceiveRequestAttemptId"`: This parameter applies only to FIFO (first-in-first-out)
  queues. The token used for deduplication of ReceiveMessage calls. If a networking issue
  occurs after a ReceiveMessage action, and instead of a response you receive a generic
  error, it is possible to retry the same action with an identical ReceiveRequestAttemptId to
  retrieve the same set of messages, even if their visibility timeout has not yet expired.
  You can use ReceiveRequestAttemptId only for 5 minutes after a ReceiveMessage action.
  When you set FifoQueue, a caller of the ReceiveMessage action can provide a
  ReceiveRequestAttemptId explicitly.   If a caller of the ReceiveMessage action doesn't
  provide a ReceiveRequestAttemptId, Amazon SQS generates a ReceiveRequestAttemptId.   It is
  possible to retry the ReceiveMessage action with the same ReceiveRequestAttemptId if none
  of the messages have been modified (deleted or had their visibility changes).   During a
  visibility timeout, subsequent calls with the same ReceiveRequestAttemptId return the same
  messages and receipt handles. If a retry occurs within the deduplication interval, it
  resets the visibility timeout. For more information, see Visibility Timeout in the Amazon
  Simple Queue Service Developer Guide.  If a caller of the ReceiveMessage action still
  processes messages when the visibility timeout expires and messages become visible, another
  worker consuming from the same queue can receive the same messages and therefore process
  duplicates. Also, if a consumer whose message processing time is longer than the visibility
  timeout tries to delete the processed messages, the action fails with an error. To mitigate
  this effect, ensure that your application observes a safe threshold before the visibility
  timeout expires and extend the visibility timeout as necessary.    While messages with a
  particular MessageGroupId are invisible, no more messages belonging to the same
  MessageGroupId are returned until the visibility 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, no retries work until the original
  visibility timeout expires. As a result, delays might occur but the messages in the queue
  remain in a strict order.   The maximum length of ReceiveRequestAttemptId is 128
  characters. ReceiveRequestAttemptId can contain alphanumeric characters (a-z, A-Z, 0-9) and
  punctuation (!\"#%&'()*+,-./:;<=>?@[]^_`{|}~). For best practices of using
  ReceiveRequestAttemptId, see Using the ReceiveRequestAttemptId Request Parameter in the
  Amazon Simple Queue Service Developer Guide.
- `"VisibilityTimeout"`: The duration (in seconds) that the received messages are hidden
  from subsequent retrieve requests after being retrieved by a ReceiveMessage request.
- `"WaitTimeSeconds"`: The duration (in seconds) for which the call waits for a message to
  arrive in the queue before returning. If a message is available, the call returns sooner
  than WaitTimeSeconds. If no messages are available and the wait time expires, the call
  returns successfully with an empty list of messages.  To avoid HTTP errors, ensure that the
  HTTP response timeout for ReceiveMessage requests is longer than the WaitTimeSeconds
  parameter. For example, with the Java SDK, you can set HTTP transport settings using the
  NettyNioAsyncHttpClient for asynchronous clients, or the  ApacheHttpClient for synchronous
  clients.

unformatted text. The following Unicode characters are allowed:  #x9 | #xA | #xD | #x20 to
#xD7FF | #xE000 to #xFFFD | #x10000 to #x10FFFF  Any characters not included in this list

  #x10000 to #x10FFFF  Any characters not included in this list will be rejected. For more
  information, see the W3C specification for characters.
- `queue_url`: The URL of the Amazon SQS queue to which a message is sent. Queue URLs and
  names are case-sensitive.

# Optional Parameters
Optional parameters can be passed as a `params::Dict{String,<:Any}`. Valid keys are:
- `"DelaySeconds"`:  The length of time, in seconds, for which to delay a specific message.
  Valid values: 0 to 900. Maximum: 15 minutes. Messages with a positive DelaySeconds value
  become available for processing after the delay period is finished. If you don't specify a
  value, the default value for the queue applies.   When you set FifoQueue, you can't set
  DelaySeconds per message. You can set this parameter only on a queue level.
- `"MessageAttribute"`: Each message attribute consists of a Name, Type, and Value. For
  more information, see Amazon SQS Message Attributes in the Amazon Simple Queue Service
  Developer Guide.
- `"MessageDeduplicationId"`: This parameter applies only to FIFO (first-in-first-out)
  queues. The token used for deduplication of sent messages. If a message with a particular
  MessageDeduplicationId is sent successfully, any messages sent with the same
  MessageDeduplicationId are accepted successfully but aren't delivered during the 5-minute
  deduplication interval. For more information, see  Exactly-Once Processing in the Amazon
  Simple Queue Service 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.   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.     The MessageDeduplicationId is available to the consumer of the
  message (this can be useful for troubleshooting delivery issues). If a message is sent
  successfully but the acknowledgement is lost and the message is resent with the same
  MessageDeduplicationId after the deduplication interval, Amazon SQS can't detect duplicate
  messages. Amazon SQS continues to keep track of the message deduplication ID even after the
  message is received and deleted.  The maximum length of MessageDeduplicationId is 128
  characters. MessageDeduplicationId can contain alphanumeric characters (a-z, A-Z, 0-9) and
  punctuation (!\"#%&'()*+,-./:;<=>?@[]^_`{|}~). For best practices of using
  MessageDeduplicationId, see Using the MessageDeduplicationId Property in the Amazon Simple
  Queue Service Developer Guide.
- `"MessageGroupId"`: This parameter applies only to FIFO (first-in-first-out) queues. The
  tag that specifies that a message belongs to a specific message group. Messages that belong
  to the same message group are processed in a FIFO manner (however, messages in different
  message groups might be processed out of order). To interleave multiple ordered streams
  within a single queue, use MessageGroupId values (for example, session data for multiple
  users). In this scenario, multiple consumers can process the queue, but the session data of
  each user is processed in a FIFO fashion.   You must associate a non-empty MessageGroupId
  with a message. If you don't provide a MessageGroupId, the action fails.    ReceiveMessage
  might return messages with multiple MessageGroupId values. For each MessageGroupId, the
  messages are sorted by time sent. The caller can't specify a MessageGroupId.   The length
  of MessageGroupId is 128 characters. Valid values: alphanumeric characters and punctuation
  (!\"#%&'()*+,-./:;<=>?@[]^_`{|}~). For best practices of using MessageGroupId,
  see Using the MessageGroupId Property in the Amazon Simple Queue Service Developer Guide.
  MessageGroupId is required for FIFO queues. You can't use it for Standard queues.
- `"MessageSystemAttribute"`: The message system attribute to send. Each message system
  attribute consists of a Name, Type, and Value.    Currently, the only supported message
  system attribute is AWSTraceHeader. Its type must be String and its value must be a
  correctly formatted AWS X-Ray trace header string.   The size of a message system attribute
  doesn't count towards the total size of a message.

    send_message_batch(queue_url, send_message_batch_request_entry)
    send_message_batch(queue_url, send_message_batch_request_entry, params::Dict{String,<:Any})

Delivers up to ten messages to the specified queue. This is a batch version of
SendMessage. For a FIFO queue, multiple messages within a single batch are enqueued in the
order they are sent. The result of sending 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. The maximum allowed individual message size and the maximum total
payload size (the sum of the individual lengths of all of the batched messages) are both
256 KB (262,144 bytes).  A message can include only XML, JSON, and unformatted text. The
following Unicode characters are allowed:  #x9 | #xA | #xD | #x20 to #xD7FF | #xE000 to
#xFFFD | #x10000 to #x10FFFF  Any characters not included in this list will be rejected.
For more information, see the W3C specification for characters.  If you don't specify the
DelaySeconds parameter for an entry, Amazon SQS uses the default value for the queue. 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:  &AttributeName.1=first   &AttributeName.2=second

# Arguments

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
Amazon SQS system. Changes made to the MessageRetentionPeriod attribute can take up to 15
minutes.    In the future, new attributes might be added. If you write code that calls this

# Arguments
- `attribute`: 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 length of time, in seconds, for which the delivery of all messages in
  the queue is delayed. Valid values: An integer from 0 to 900 (15 minutes). Default: 0.
  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). Default: 262,144 (256 KiB).     MessageRetentionPeriod – The length of time, in
  seconds, for which Amazon SQS retains a message. Valid values: An integer representing
  seconds, from 60 (1 minute) to 1,209,600 (14 days). Default: 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 in the Amazon IAM User Guide.
  ReceiveMessageWaitTimeSeconds – The length of time, in seconds, for which a
  ReceiveMessage  action waits for a message to arrive. Valid values: An integer from 0 to 20
  (seconds). Default: 0.     RedrivePolicy – The string that includes the parameters for
  the dead-letter queue functionality of the source queue as a JSON object. For more
  information about the redrive policy and dead-letter queues, see Using Amazon SQS
  Dead-Letter Queues in the Amazon Simple Queue Service Developer Guide.
  deadLetterTargetArn – The Amazon Resource Name (ARN) of the dead-letter queue to which
  Amazon SQS moves messages after the value of maxReceiveCount is exceeded.
  maxReceiveCount – The number of times a message is delivered to the source queue before
  being moved to the dead-letter queue. When the ReceiveCount for a message exceeds the
  maxReceiveCount for a queue, Amazon SQS moves the message to the dead-letter-queue.    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, in seconds. Valid values: An integer from 0 to 43,200 (12
  hours). Default: 30. For more information about the visibility timeout, see Visibility
  Timeout in the Amazon Simple Queue Service Developer Guide.   The following attributes
  apply only to server-side-encryption:    KmsMasterKeyId – The ID of an AWS-managed
  customer master key (CMK) for Amazon SQS or a custom CMK. For more information, see Key
  Terms. While the alias of the AWS-managed CMK for Amazon SQS is always alias/aws/sqs, the
  alias of a custom CMK can, for example, be alias/MyAlias . For more examples, see KeyId in
  the AWS Key Management Service API Reference.     KmsDataKeyReusePeriodSeconds – The
  length of time, in seconds, for which Amazon SQS can reuse a data key to encrypt or decrypt
  messages before calling AWS KMS again. An integer representing seconds, between 60 seconds
  (1 minute) and 86,400 seconds (24 hours). Default: 300 (5 minutes). A shorter time period
  provides better security but results in more calls to KMS which might incur charges after
  Free Tier. For more information, see How Does the Data Key Reuse Period Work?.    The
  following attribute applies only to FIFO (first-in-first-out) queues:
  ContentBasedDeduplication – Enables content-based deduplication. For more information,
  see Exactly-Once Processing in the Amazon Simple Queue Service Developer Guide. Note the
  following:    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.   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.       Preview: High throughput for FIFO queues   High
  throughput for Amazon SQS FIFO queues is in preview release and is subject to change. This
  feature provides a high number of transactions per second (TPS) for messages in FIFO
  queues. For information on throughput quotas, see Quotas related to messages in the Amazon
  Simple Queue Service Developer Guide. This preview includes two new attributes:
  DeduplicationScope – Specifies whether message deduplication occurs at the message group
  or queue level. Valid values are messageGroup and queue.    FifoThroughputLimit –
  Specifies whether the FIFO queue throughput quota applies to the entire queue or per
  message group. Valid values are perQueue and perMessageGroupId. The perMessageGroupId value
  is allowed only when the value for DeduplicationScope is messageGroup.   To enable high
  throughput for FIFO queues, do the following:   Set DeduplicationScope to messageGroup.
  Set FifoThroughputLimit to perMessageGroupId.   If you set these attributes to anything
  other than the values shown for enabling high throughput, standard throughput is in effect
  and deduplication occurs as specified. This preview is available in the following AWS
  Regions:   US East (Ohio); us-east-2   US East (N. Virginia); us-east-1   US West (Oregon);
  us-west-2   Europe (Ireland); eu-west-1   For more information about high throughput for
  FIFO queues, see Preview: High throughput for FIFO queues in the Amazon Simple Queue
  Service Developer Guide.
