摘要： Systems and methods are provided to produce an efficient architecture and methodology for multiple database engines to write to a shared data storage to eliminate global locking in the write process. Such systems and methods can use a common log layer between a shared data storage and computing database nodes in which write conflict detection is implemented using a write ahead log record and a log sequence number. A write-write conflict check on a write ahead log record received from a database engine of multiple database engines can be performed by conducting a comparison of a log sequence number, received with the write ahead log record from the database engine, with a global log sequence number in a hash table in the common log. The write ahead log record can be sent to the shared data storage in response to the write ahead log record passing the write-write conflict check.

摘要： The present disclosure provides an encoding and decoding device implementing an improved forward error correction, FEC, coding/ decoding method. In particular, the encoding device is configured to encode a stream of data symbols using a spatially coupled code (e.g. staircase codes, braided block codes or continuously interleaved block codes), wherein at least one generalized error location, GEL, code is used as a component code of the spatially coupled code. Accordingly, the decoding device is configured to decode a sequence of encoded symbol blocks using a spatially coupled code, wherein at least one GEL code is used as a component code of the spatially coupled code. Thereby, a suitable spatially coupled FEC code that allows for very low-latency, high-throughput, high-rate applications with a low-complexity decoding procedure, and allows for mitigation of the error-floor, is designed.

摘要： A system and method for improved online transaction processing (OLTP) in a sharded database is provided. Overhead associated with a global transaction manager is reduced and scalability improved by determining whether incoming queries are single-shard transactions or multi-shard transactions. For multi-shard transactions, a distributed transaction ID (DXID) is requested from the GTM, and then forwarded with the query to one or more data notes. For single-shard transactions, the query is sent to a data node without requesting a DXID from the GTM.

摘要： This application relates to a connector and an electronic device provided with the connector. The connector includes a socket assembly and a plug assembly that are detachably connected. The socket assembly includes a connecting base. The connecting base includes a signal port and a shielding structure. The shielding structure is disposed around a peripheral edge of the signal port. The plug assembly includes a connecting head. The connecting head includes a signal terminal and a ground component. The signal terminal and the ground component are disposed side by side. When the plug assembly is fixedly connected to the socket assembly, each connecting head extends into one connecting base, the signal terminal is conducted to the signal port, and the ground component is bonded to the shielding structure. In this application, the shielding structure of the connector is disposed around peripheral edges of the signal terminal and the signal port, and forms bonding with the ground component, to form reliable shielding effect on a mating surface. This may effectively prevent a phenomenon of signal current return, avoids impact of crosstalk resonance, and improves signal transmission integrity of the connector.
