Amazon SQS Extended Client Library for Java

The Amazon SQS Extended Client Library for Java enables you to manage Amazon SQS message payloads with Amazon S3. This is especially useful for storing and retrieving messages with a message payload size greater than the current SQS limit of 256 KB, up to a maximum of 2 GB. Specifically, you can use this library to:

  • Specify whether message payloads are always stored in Amazon S3 or only when a message's size exceeds 256 KB.

  • Send a message that references a single message object stored in an Amazon S3 bucket.

  • Get the corresponding message object from an Amazon S3 bucket.

  • Delete the corresponding message object from an Amazon S3 bucket.

You can download release builds through the releases section of this project.

For more information on using the amazon-sqs-java-extended-client-lib, see our getting started guide here.
