Hello, Some questions on new and old features of Swift. Any help would be great:) Some are very basic, sorry!
1. Does Swift write two copies and then return back to the client in the 3 replica case, with third in the background? 2. This again is a stupid question, but eventually consistent for an object is a bit confusing, unless it is updated. If it is created, it is either there or not and you cannot update the data within the object. Maybe a POST can change the metadata? Or the container listing shows its there but the actual object never got there? Those are the only cases I can think of. 3. Once an object has been written, when and how is the container listing, number of bytes, account listing (if new container created) etc updated? Is there something done in the path of the PUT to indicate this object belongs to a particular container and the number of bytes etc is done in the background? A little clarification would help:) 4. For the global clusters, is the object ring across regions or is it the same with containers and accounts also? 5. For containers in global clusters, if a client queries the container metadata from another site, is there a chance of it getting the old metadata? With respect to the object itself, the eventually consistent part is a bit confusing for me:) MW _______________________________________________ Mailing list: http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack Post to : openstack@lists.openstack.org Unsubscribe : http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack
