Publishing large messages with Amazon SNS and Amazon S3 - Amazon Simple Notification Service

Publishing large messages with Amazon SNS and Amazon S3

To publish large Amazon SNS messages, you can use the Amazon SNS Extended Client Library for Java, or the Amazon SNS Extended Client Library for Python. These libraries are useful for messages that are larger than the current maximum of 256 KB, with a maximum of 2 GB. Both libraries save the actual payload to an Amazon S3 bucket, and publish the reference of the stored Amazon S3 object to the Amazon SNS topic. Subscribed Amazon SQS queues can use the Amazon SQS Extended Client Library for Java to de-reference and retrieve payloads from Amazon S3. Other endpoints such as Lambda can use the Payload Offloading Java Common Library for AWS to de-reference and retrieve the payload.

Note

The Amazon SNS Extended Client Libraries are compatible with both standard and FIFO topics.
