AWS CLI Command Reference

[ aws . sqs ]

send-message-batch

Description

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).

Warning

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

Options

--queue-url (string)

The URL of the Amazon SQS queue to which batched messages are sent.

Queue URLs and names are case-sensitive.

--entries (list)

A list of `` SendMessageBatchRequestEntry `` items.

(structure)

Contains the details of a single Amazon SQS message along with an Id .

Id -> (string)

An identifier for a message in this batch used to communicate the result.

Note

The Id s of a batch request need to be unique within a request.

This identifier can have up to 80 characters. The following characters are accepted: alphanumeric characters, hyphens(-), and underscores (_).

MessageBody -> (string)

The body of the message.

DelaySeconds -> (integer)

The length of time, in seconds, for which a specific message is delayed. 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 is applied.

Note

When you set FifoQueue , you can’t set DelaySeconds per message. You can set this parameter only on a queue level.

MessageAttributes -> (map)

Each message attribute consists of a Name , Type , and Value . For more information, see Amazon SQS message attributes in the Amazon SQS Developer Guide .

Name -> (string)

Value -> (structure)

The user-specified message attribute value. For string data types, the Value attribute has the same restrictions on the content as the message body. For more information, see `` SendMessage .``

Name , type , value and the message body must not be empty or null. All parts of the message attribute, including Name , Type , and Value , are part of the message size restriction (256 KB or 262,144 bytes).

StringValue -> (string)

Strings are Unicode with UTF-8 binary encoding. For a list of code values, see ASCII Printable Characters .

BinaryValue -> (blob)

Binary type attributes can store any binary data, such as compressed data, encrypted data, or images.

StringListValues -> (list)

Not implemented. Reserved for future use.

(string)

BinaryListValues -> (list)

Not implemented. Reserved for future use.

(blob)

DataType -> (string)

Amazon SQS supports the following logical data types: String , Number , and Binary . For the Number data type, you must use StringValue .

You can also append custom labels. For more information, see Amazon SQS Message Attributes in the Amazon SQS Developer Guide .

MessageSystemAttributes -> (map)

The message system attribute to send Each message system attribute consists of a Name , Type , and Value .

Warning

  • Currently, the only supported message system attribute is AWSTraceHeader . Its type must be String and its value must be a correctly formatted X-Ray trace header string.

  • The size of a message system attribute doesn’t count towards the total size of a message.

Name -> (string)

Value -> (structure)

The user-specified message system attribute value. For string data types, the Value attribute has the same restrictions on the content as the message body. For more information, see `` SendMessage .``

Name , type , value and the message body must not be empty or null.

StringValue -> (string)

Strings are Unicode with UTF-8 binary encoding. For a list of code values, see ASCII Printable Characters .

BinaryValue -> (blob)

Binary type attributes can store any binary data, such as compressed data, encrypted data, or images.

StringListValues -> (list)

Not implemented. Reserved for future use.

(string)

BinaryListValues -> (list)

Not implemented. Reserved for future use.

(blob)

DataType -> (string)

Amazon SQS supports the following logical data types: String , Number , and Binary . For the Number data type, you must use StringValue .

You can also append custom labels. For more information, see Amazon SQS Message Attributes in the Amazon SQS Developer Guide .

MessageDeduplicationId -> (string)

This parameter applies only to FIFO (first-in-first-out) queues.

The token used for deduplication of messages within a 5-minute minimum deduplication interval. If a message with a particular MessageDeduplicationId is sent successfully, subsequent messages with the same MessageDeduplicationId are accepted successfully but aren’t delivered. For more information, see 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.

  • 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.

Note

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 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 SQS Developer Guide .

MessageGroupId -> (string)

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 SQS Developer Guide .

Warning

MessageGroupId is required for FIFO queues. You can’t use it for Standard queues.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command’s default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination.

--output (string)

The formatting style for command output.

  • json

  • text

  • table

  • yaml

  • yaml-stream

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on

  • off

  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

--cli-binary-format (string)

The formatting style to be used for binary blobs. The default format is base64. The base64 format expects binary blobs to be provided as a base64 encoded string. The raw-in-base64-out format preserves compatibility with AWS CLI V1 behavior and binary values must be passed literally. When providing contents from a file that map to a binary blob fileb:// will always be treated as binary and use the file contents directly regardless of the cli-binary-format setting. When using file:// the file contents will need to properly formatted for the configured cli-binary-format.

  • base64

  • raw-in-base64-out

--no-cli-pager (boolean)

Disable cli pager for output.

--cli-auto-prompt (boolean)

Automatically prompt for CLI input parameters.

--no-cli-auto-prompt (boolean)

Disable automatically prompt for CLI input parameters.

Examples

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal’s quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .
