AWS – Amazon S3 Express One Zone now supports the ability to append data to an object

Amazon S3 Express One Zone now supports the ability to append data to an object. For the first time, applications can add data to an existing object in S3.

Applications that continuously receive data over a period of time need the ability to add data to existing objects. For example, log-processing applications continuously add new log entries to the end of existing log files. Similarly, media-broadcasting applications add new video segments to video files as they are transcoded and then immediately stream the video to viewers. Previously, these applications needed to combine data in local storage before copying the final object to S3. Now, applications can directly append new data to existing objects and then immediately read the object, all within S3 Express One Zone.

You can append data to objects in S3 Express One Zone in all AWS Regions where the storage class is available. You can get started using the AWS SDK, the AWS CLI, or Mountpoint for Amazon S3 (version 1.12.0 or higher). To learn more, visit the S3 User Guide.
