Specifies whether the error happened due to the caller of the batch API action.Īn error code representing why the action failed on this entry.Ī message explaining why the action failed on this entry. Any component can later retrieve the messages programmatically using the Amazon SQS API. Messages can contain up to 256 KB of text in any format. This first script sends an XML message to a queue named TradeStatus.fifo, and the second script receives the message from the same queue. Gives a detailed description of the result of an action on each entry in the request. This example is using boto3, the AWS SDK for Python. Represents a successfully deleted message. The name of the message attribute, where N is the index.Response Structureįor each message in the batch, the response contains a DeleteMessageBatchResultEntry tag if the message is deleted or a BatchResultErrorEntry tag if the message can’t be deleted.Ī list of DeleteMessageBatchResultEntry items.Įncloses the Id of an entry in DeleteMessageBatch. SequenceNumber – Returns the value provided by Amazon SQS. Messages with the same MessageGroupId are returned in sequence. MessageGroupId – Returns the value provided by the producer that calls the SendMessage action. MessageDeduplicationId – Returns the value provided by the producer that calls the SendMessage action. Only one server-side encryption option is supported per queue (for example, SSE-KMS or SSE-SQS). SqsManagedSseEnabled – Enables server-side queue encryption using SQS owned encryption keys. SentTimestamp – Returns the time the message was sent to the queue ( epoch time in milliseconds). deletequeue ( kwargs) Deletes the queue specified by the QueueUrl, regardless of the queue’s contents. These attributes include:ĪpproximateFirstReceiveTimestamp – Returns the time the message was first received from the queue ( epoch time in milliseconds).ĪpproximateReceiveCount – Returns the number of times a message has been received across all queues but not deleted.ĪWSTraceHeader – Returns the X-Ray trace header string.įor a user, returns the user ID, for example ABCDEFGHI1JKLMNOPQ23R.įor an IAM role, returns the IAM role ID, for example ABCDE1F2GH3I4JK5LMNOP:i-a123b456. receive_messages ( AttributeNames =, MessageAttributeNames =, MaxNumberOfMessages = 123, VisibilityTimeout = 123, WaitTimeSeconds = 123, ReceiveRequestAttemptId = 'string' ) Parameters :Ī list of attributes that need to be returned along with each message. Depending on the configuration of the queue, the message might be sent to the dead-letter queue. For more information, see Visibility Timeout in the Amazon SQS Developer Guide.Ī message that isn’t deleted or a message whose visibility isn’t extended before the visibility timeout expires counts as a failed receive. If you don’t include the parameter, the overall visibility timeout for the queue is used for the returned messages. The parameter is applied to the messages that Amazon SQS returns in the response. You can provide the VisibilityTimeout parameter in your request. For more information, see Queue and Message Identifiers in the Amazon SQS Developer Guide. The receipt handle is the identifier you must provide when deleting the message. The MessageId you received when you sent the message to the queue. If this happens, repeat the request.įor each message returned, the response includes the following:Īn MD5 digest of the message body. If the number of messages in the queue is extremely small, you might not receive any messages in a particular ReceiveMessage response. You can see this action in context in the following code examples: Publish messages to queues. Action examples are code excerpts from larger programs and must be run in context. The following code examples show how to delete a batch of messages from an Amazon SQS queue. 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. Delete a batch of messages from an Amazon SQS queue using an AWS SDK. Thus, only the messages on the sampled machines are returned. Short poll is the default behavior where a weighted random set of machines is sampled on a ReceiveMessage call. For more information, see Amazon SQS Long Polling in the Amazon SQS Developer Guide. Using the WaitTimeSeconds parameter enables long-poll support. ![]() ![]() Retrieves one or more messages (up to 10), from the specified queue. Before creating a queue, you must first get the SQS service resource: It is possible to look up a queue by its name. Queue / Action / receive_messages receive_messages # SQS.Queue. The examples below will use the queue name.
