Description

There are update operations that can be performed for Volume, Bucket and Key.

While Key records the modification time, Volume and & Bucket do not capture this.

 

This Jira proposes to add the required field to Volume and Bucket in order to capture the modficationTime.
(The modification time of this Jira only applies to volume/bucket metadata modification itself, not covering key changes under the volume bucket.)
