Amazon Simple Queue Service (SQS) is a fully managed message queuing service that enables you to decouple and scale microservices, distributed systems, and serverless applications. SQS eliminates the complexity and overhead associated with managing and operating message-oriented middleware, and empowers developers to focus on differentiating work.
For more information, visit the official AWS SQS page.
When working with AWS SQS, you might encounter an error code: AWS.SimpleQueueService.MessageTooLong. This error indicates that the message you are trying to send to the queue exceeds the maximum allowed size.
The AWS.SimpleQueueService.MessageTooLong error occurs when the message size exceeds the limit set by AWS SQS. As of the current AWS guidelines, the maximum message size allowed is 256 KB.
This error typically occurs when attempting to send large payloads that exceed the 256 KB limit. This can happen if the message includes large data objects or if the data is not properly compressed before sending.
To resolve this issue, ensure that your message size is within the 256 KB limit. Consider the following strategies:
Before sending a message, validate its size to ensure it does not exceed the limit. Here is a sample code snippet in Python:
import boto3
import sys
sqs = boto3.client('sqs')
queue_url = 'YOUR_QUEUE_URL'
message_body = 'YOUR_MESSAGE_BODY'
if sys.getsizeof(message_body) > 262144: # 256 KB
raise ValueError("Message size exceeds 256 KB")
response = sqs.send_message(QueueUrl=queue_url, MessageBody=message_body)
print("Message sent with ID:", response['MessageId'])
By understanding the limitations of AWS SQS and implementing strategies to manage message sizes, you can effectively avoid the AWS.SimpleQueueService.MessageTooLong error. For more detailed guidance, refer to the AWS SQS Developer Guide.
