Abstract: This application provides a method includes: in response to a first indication, indicating a target second node in at least one second node to perform a target operation, where the first indication indicates to update a base table, the base table is stored in the at least one second node in a distributed manner, and the target operation is used to update the base table; receiving target information from the target second node, where the target information is used to update a global secondary index of the base table, and the global secondary index is stored in at least one third node in a distributed manner; and indicating, based on the target information, a target third node in the at least one third node to update the global secondary index.

Abstract: Systems and methods for a battery pack are disclosed. A battery pack tab cooling system is disclosed that includes a pouch cell comprising a first tab and a second tab. The battery pack tab cooling system also includes an enclosure configured to contain a cooling material. The first tab and the second tab extend from the pouch cell into the enclosure and are in contact with the cooling material. A method of manufacturing a battery pack that includes forming the battery pack, the battery pack comprising and cooling the at least one of the first tab and the second tab to cool the pouch cell.

Abstract: A mobile phone may include a display, wireless communication circuitry, a battery, and an enclosure enclosing the display, the wireless communication circuitry, and the battery. The enclosure may include a front cover formed from a transparent material and defining a front exterior surface of the mobile phone, a rear cover formed from a glass material and defining a rear exterior surface of the mobile phone, and a first housing component including a first wall section defining a first side exterior surface of the mobile phone, a second wall section defining a second side exterior surface opposite to the first side exterior surface, and a mid-chassis section extending between the first wall section and the second wall section.
