Amazon S3 OCF Connector: Version 3.9.3


Support for Custom Inventory Folder Name During Inventory Configuration

You can now provide a custom inventory folder name while configuring the inventory. Earlier, the connector didn’t allow metadata extraction in an existing bucket without the folder named inventory within the destination bucket.

You can provide the inventory bucket name or path in the Provide inventory bucket or path section of the Metadata Extraction tab. (AL-156991)
