This application provides a method for determining a foldable screen included angle and associated devices of the method. The method includes: acquiring, by an acceleration sensor, an initial acceleration signal at time t, and acquiring, by a gyroscope sensor, an initial angular velocity signal at time t; performing first preprocessing on the initial acceleration signal at time t to determine a target value of a gravitational acceleration signal at time t, and performing second preprocessing on the initial angular velocity signal at time t to determine an intermediate angular velocity signal at time t; detecting a state of the foldable screen according to the gravitational acceleration signals to determine the state of the foldable screen at time t; and determining the included angle corresponding to the foldable screen at time t according to the state of the foldable screen at time t.

Method for determining foldable screen included angle and associated devices of method

An object information processing method includes obtaining an information creation request. The information creation request carries a first address identifier of a target object. The target object includes a subdirectory or a sub-file. The method further includes determining a second address identifier of a parent directory to which the target object belongs according to the first address identifier, searching for an information storage area storing metadata of the parent directory according to the second address identifier, and performing data updating for the information storage area according to the first address identifier to create an association relationship between the parent directory and the target object in the metadata.

Object information processing method and apparatus, and storage medium

A data synchronization method, system and apparatus are provided. The method includes receiving a request including data to be uploaded, from a client, and responding to the request after data is successfully obtained from the client, and storing the obtained data. For data whose size is less than a threshold value, a synchronization request is sent to a standby server to request the standby server to store the data. Otherwise a second type work log, including information indicating that data that has not been synchronized, is generated and stored. Data whose size is greater than or equal to the threshold value is not synchronized immediately, but is recorded in the work log. In some cases, data whose size is less than the threshold value, but fails to be synchronized, is recorded in the work log. Synchronization of this data may be subsequently completed according to the work log, so that the synchronization of this data can avoid affecting synchronization of other data. A first-type work log comprising information about the data may be generated and stored in response to the data being synchronized to the standby server successfully. Data that has not been synchronized to the standby server, according to the indication information, may be locally read and the data sent to the standby server to be stored. Data may be sent to the standby server to replace other data, in response to verification codes, such as hash codes, being inconsistent. The first and second work logs may also be sent to a log backup device. Responding to the uploading request and sending data to the standby server may occur asynchronously.

Data synchronization method, system, and apparatus using a work log for synchronizing data greater than a threshold value

Implementation manners of the present invention provide a data storage method and apparatus. A fixed-length key and a value thereof are stored into a first data block, where the storing a fixed-length key includes: uniformly storing a common prefix of each fixed-length key, and separately storing a remainder part of each fixed-length key after the common prefix is removed; and a variable-length key and a length thereof are stored into a second data block, where the storing a variable-length key includes: storing a variable-length key of a base-key type in a full storage manner, and performing prefix compression on a variable-length key of a prefix-compressed key type.
