Hi Gareth: The process of update object count to container db is synchronized. After the DiskFile finish writing the data to disk, the object-server will make a request to container servers and update the object count. If the request failed, the request will be serialized on the disk, and the object-update will update it to container servers asynchronously. The process of update object count from container db to account db is asynchronized. The container-updater will loop all the container db files in disk and update the object count the account servers. 2013/10/22 Gareth <academicgareth at gmail.com> > Hi > > How does Swift update container object count or account object count after > PUT an object?
