What is the maximum size of SQS messages in terms of text content?

The maximum size of a message that can be sent using Amazon Simple Queue Service (SQS) is 256 KB. This limit includes both the message body and any attributes associated with the message. It's important to recognize that this size restriction ensures messages can be quickly processed and retrieved without overwhelming the SQS infrastructure.

Understanding this limit is critical when designing applications that utilize SQS for message queuing. If your application needs to handle larger messages, you would need to implement a different strategy, such as breaking down larger payloads into smaller messages or using services like Amazon S3 to store larger data and sending a reference to that data in the SQS message.

Overall, knowing that the message size is capped at 256 KB helps developers make informed decisions about message formats and processing logic when integrating SQS into their applications.
