Abstract: Techniques are disclosed for generating a dynamic upgrade prediction. The prediction includes generating an initial upgrade prediction for an upgrade to be performed on a subset of component nodes; performing a real time progress review, using a centralized management node, of the upgrade, wherein each of the component nodes includes a number of stages; performing an upgrade duration comparison between the initial upgrade prediction and a real time upgrade time for a subset of the stages; and generating an updated upgrade prediction for the multi-component product upgrade based on the comparison between the initial upgrade prediction and the real time upgrade time.

Abstract: A retention-based consistent hash ring process defines each file name in the system to include its expiration date (or time) as a prefix or suffix that is stored and indexed as metadata. The process uses a virtual node to represent adjacent expiration days to create virtual nodes based on individual days of the week. Each physical node contains the same number of labeled virtual nodes, and the consistent hash ring process is used to move files with the same expiration day to different physical nodes by looking for next labeled virtual nodes on the hash ring. This provides a way to locate the virtual node storage location by specifying a file's expiration date as part of the key used in the hash ring process, and distributes files that may otherwise be assigned to the same physical node through a backup policy.

Abstract: A method for manufacturing a three-dimensional (3D) footwear product may be provided. The method may include obtaining foot feature data. The foot feature data may include a size of a foot. The method may also include constructing a planar model of the 3D footwear product based on the foot feature data. The planar model may include a body region and a connection structure connected to the body region. The method may further include printing a planar product of the 3D footwear product using a 3D printing method based on the planar model.

Abstract: The application discloses a hollowed-out printed object and a 3D printing support, a 3D printing support construction method and a 3D printing method of the hollowed-out printed object. At least one end of the 3D printing support of the hollowed-out printed object is connected to the hollowed-out printed object; the support includes a main body and a connecting portion connected to the hollowed-out printed object; a joint between at least part of the connecting portion and the hollowed-out printed object is located inside the hollowed-out printed object.
