#10046 assigned enhancement

Dynamic Large Object (DLO) support

Reported by: hugokuo Owned by: dkocher
Priority: normal Milestone:
Component: openstack Version: 6.2.2
Severity: normal Keywords: #swift #dlo #largeobject
Cc: Architecture:


OS: MacOS Cyberduck : 6.2.2 OpenStack Swift : 2.12

  • While Cyberduck browse a Swift container which has DLO manifest. The file size shows Zero Byte.B/c the container list API with size returns the manifest file size instead of the actual files's aggregated file size.
  • You can download the DLO object but the transfer log shows it's failed. But the file is downloaded correctly to local already. The md5sum matches the original source. While check the stat of the DLO manifest, the Etag is from the hash of all segments's md5. Hence the Etag of the manifest is not the md5sum of source file.
