Abstract: When performing a recycling operation on a storage device, a storage system may use or create a data buffer in the storage device, and designate the data buffer to temporarily store data of data blocks to be recycled in the storage device using direct memory access (DMA) operations that are performed internally in the storage device, without the need of reading the data of the data blocks from the storage device and writing the data into a host memory of the storage system, thereby saving or reducing the consumptions of the communication bandwidth of a communication channel between the storage system and the storage device, and the memory bandwidth of the host memory.

Abstract: A storage engine may be configured to employ different formats for index fragments and index entries of respective records in the index fragments based at least in part on record properties of the respective records in the index fragments, to reduce an amount of memory space that is consumed or used for storing the index fragments in a memory associated with the storage engine, without compromising the efficiency of searching the records stored in a storage device. Using different formats for index fragments covering records of different record properties, the storage engine may further be configured to create, maintain, and update index mappings for records stored or included in the storage device, to provide functionalities of point-lookup, range query, deletion, and additions of the records in the storage device.

Abstract: A method for managing a region tag comprises: acquiring region identifier information of a geographic region; acquiring an attribute evaluation tag of the geographic region by a user in the geographic region and a time identifier of the attribute evaluation tag; integrating the region identifier information, the attribute evaluation tag, and the time identifier thereof into a region tag of the geographic region; clustering region tags to generate a region time period tag of the geographic region for a time period based on that each region tag comprises the region identifier information of the geographic region and a time identifier within the time period, wherein the region time period tag of the geographic region for the time period corresponds to a function attribute of the geographic region for the time period; and outputting region time period tags of the geographic region for time periods, respectively.

Abstract: A storage record engine implemented on a storage system is provided. The storage record engine further organizes hosted storage of the storage system into superblocks and chunks organized by respective metadata, the chunks being further organized into chunk segments amongst superblocks. Persistent storage operations may cause modifications to the metadata, which may be recorded in a transaction log, records of which may be replayed to commit the modifications to hosted storage. The replay functionality may establish recovery of data following a system failure, wherein replay of records of transaction logs in a fashion interleaved with checkpoint metadata avoids preemption of normal storage device activity during a recovery process, and improves responsiveness of the storage system from the perspective of end devices.

Abstract: The disclosed embodiments describe a method, apparatus, and system for pushing information. In one embodiment, the method comprises: receiving dynamic spatio-temporal behavior data of a moving individual; conducting an analysis according to historical dynamic spatio-temporal behavior data of the moving individual to acquire spatio-temporal behavioral characteristics of the moving individual; determining appropriate information as matching information for the moving individual according to the spatio-temporal behavioral characteristics of the moving individual in combination with dynamic spatio-temporal behavior data of the moving individual at a current time; and sending the matching information to the moving individual. In the method of the disclosure, behavioral characteristics of a moving individual are analyzed to obtain habit and preference characteristics of the moving individual. Targeted push information is sent, thereby solving the problem of pushed information having less diversified, targeted, and not so accurate content.

Abstract: A client device may transmit a data stream including an object (such as a data file or record) to a storage system for storing the object in a storage device. In response to receiving the data stream, the storage system may store or write data of the object into a plurality of logical blocks of the storage device with an end-to-end data protection based at least in part on a comparison of a combination of check codes of a header of the object, the object and padding data with a combination of a plurality of check codes that are generated separately for metadata associated with the object and corresponding parts of the object stored in the plurality of logical blocks. The storage system may further provide an end-to-end data protection for reading data of an object stored in multiple logical blocks of a storage device.
