I am using the IBM Cloud Object Storage with Swift API on IBM Bluemix as seen here https://console.bluemix.net/catalog/infrastructure/object-storage-group.
I need to get the newest version of an object, or to know if it was deleted. To do so I use the X-Newest header flag in the request, but still I can get an object that was already deleted. Is there a known problem with this flag? Is it supported by the storage service? If it is, can you help to investigate why it happens?
Problematic scenario (Swift local client):
- add an object
- delete this object
- pull this object (Get or Head) with
X-Newestflag
and expect always to get "Object Not found" 404 status code (because it was deleted in the previous step). But in reality, sometimes I get this object back although it was deleted. Swift is eventually consistent, and without this flag, it would be a normal behavior. But with this flag, I should not get old versions of the object.
Do you know why it happens?
