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: Data storage and calling methods and devices are provided. One of the methods includes: receiving first motion data and business data; establishing an association relationship between the first motion data and the business data and storing the association relationship; receiving second motion data; and determining first motion data that matches the second motion data, and returning, to a sender of the second motion data, business data associated with the matched first motion data.

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: A dialog generation method includes: training a sequence to sequence (seq2seq)-based dialog model using a loss function including topic range constraint information; and generating a dialog using the trained dialog model. With the dialog generation method, topic range constraint information is introduced in the process of dialog model training using a loss function including the topic range constraint information, thus helping to prevent the trained model from producing low-quality meaningless replies.

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.

Abstract: Methods and systems for in-memory metadata reduction in cloud storage system are provided. According to an aspect, a method comprises receiving a first command to write a data stream to a storage device; writing the data stream into a plurality of fragments having logical addresses corresponding to physical addresses on the storage device; and generating an index for individual fragment of the plurality of fragments, the index indicating information to locate the physical addresses of the individual fragment. Individual records in the individual fragment have a same pre-set logical size and all individual records in the individual fragment are continuous, and the index indicates the information including at least: an offset value of the individual record in the individual fragment; the pre-set logical size of the individual record; and a pre-set physical size of the individual record.

Abstract: A storage engine may be configured to receive data including a plurality of records from a client device, and generate a plurality of record headers for the plurality of records. The storage engine may then transfer a group of record headers of the plurality of record headers to a storage device to cause the storage device to store the group of record headers consecutively in a data sector of the storage device, and further transfer a subset of payload data of one or more records associated with the group of record headers to the storage device to cause the storage device to store the one or more records after the group of record headers in the data sector of the storage device.
