Methods, systems, and devices for data management are described. A data management system (DMS) may receive a synchronization request to back up a set of files from a source database to a target database including a set of nodes. In some cases, each node of the target database may support storage of a set of data stripes, and a data stripe may include a logical subdivision of a file. The DMS may back up the set of files to the target database. The DMS may determine that a most recent data wedge is incompletely filled at a time corresponding to receiving the synchronization request, where a data wedge represents a cross section of data across multiple data chunks of a corresponding data stripe. The DMS may then generate a file including an indication of one or more data stripes corresponding to the set of files.

The application provides a multi-file synchronization method and an electronic device. The method comprises the following steps: a client first determines the aging degree of a plurality of source file copies and the data volume of synchronization data when synchronizing the plurality of source file copies, and then determines the synchronization priority of the plurality of source file copies based on the aging degree and the data volume of the synchronization data, and finally the client synchronizes the plurality of source file copies according to the synchronization priority. The multi-file synchronization method provided by the application can comprehensively consider the aging degree of the source file copies and the data volume of the synchronization data, thereby avoiding the situation that the client always synchronizes the source file copies with small synchronization data first and then synchronizes the source file copies with large synchronization data which have not been synchronized for a long time, and reducing the average synchronization time.

The application relates to the technical field of database backup and synchronization, in particular to a database master-slave file adaptive fast synchronization method, which comprises the following steps: performing difference evaluation based on the meta information of the database master-slave files, directly adopting a record-by-record synchronization mode if the overall difference is too large, or entering an incremental synchronization mode; the incremental synchronization identifies inconsistent blocks by comparing the check values of the data blocks and counts the number of the inconsistent blocks; the system respectively estimates the total time consumption of the two synchronization modes according to performance parameters, the total block number, the inconsistent block number and the total record number; a secondary decision is made by comparing the estimated time consumption, and the scheme with shorter time consumption is selected for execution; and the final consistency verification is performed on the master database file and the backup database file. Through the multi-layer threshold value judgment and the dynamic time consumption estimation model, the application intelligently selects the record-by-record synchronization or the block incremental synchronization strategy, guarantees the data consistency, and significantly improves the efficiency of the database master-slave file synchronization.

The method includes: starting a main control thread and multiple sub-threads in a process pool to synchronize the directory tree file; synchronizing non-directory files through the main control thread; identifying and encapsulating each subdirectory file under the source directory of the directory tree file using a traversal algorithm to obtain an independent task unit corresponding to each subdirectory file; and executing the independent task unit corresponding to each subdirectory file through the multiple parallel sub-threads to synchronize the subdirectory file. This scheme achieves efficient parallel synchronization of directory tree files, ensures the independence of subdirectory synchronization through the encapsulation of independent task units, and improves overall synchronization efficiency and reliability through multi-threaded processing.

This invention proposes a telemetry information acquisition and storage method based on lock-free writing and a double-buffered snapshot mechanism. The method includes: predefining a telemetry field table, generating channel enumeration, field description tables, and total record length; the business process writing business telemetry data lock-free through a shared memory double buffer; the acquisition and storage process periodically performing snapshot flipping to obtain consistent business data snapshots, while simultaneously acquiring SoC and FPGA telemetry data, merging and encoding them into headless fixed-length binary records according to the field description table; asynchronously writing the records to a file, and managing synchronization, round-robin, and circular queues according to a preset strategy.

This application belongs to the field of automotive technology and discloses a file synchronization system and method. This application generates a hardware interrupt signal when a change in electrical signal is detected during the insertion of a USB device at the hardware layer. Then, the kernel layer identifies the device type of the USB device and creates a block device node based on the device type. Next, the native layer performs a file system mount operation based on the detected file system type. Finally, the framework layer broadcasts information carrying the device path corresponding to the mount operation to the application layer. The application layer then displays the file list corresponding to the USB device based on the device path information. This application, through a complete event transmission chain from the hardware layer, kernel layer, native layer, framework layer, and application layer, ensures that the file list in the USB device remains consistent with the actual state even with frequent USB device insertion and removal.

The present application relates to the technical field of computers, and in particular relates to a multi-repository integration construction method and device, equipment and medium. The present application uses descriptors as configuration carriers to centrally manage integrated information originally scattered in repositories, scripts, CI configurations and documents, thereby reducing maintenance costs and hidden faults. Secondly, based on descriptors, version constraints and cross-repository constraints are solved to generate a lock file binding an analyzer and a descriptor version, convert complex rules such as multi-variant and cross-repository compatibility into a determined and reproducible commit record number, and solve the problem of incomplete multi-repository version combination expression. Then, the lock file is used to synchronize the code to ensure that the repository combination is completely consistent in any environment, thereby avoiding version drift and construction irreproducibility from the root. Finally, combined with the construction environment and standardized pipeline, the construction behavior is further ensured to be consistent, and multi-repository integration is stable, traceable and efficient.
