Abstract: A computing system receives a deployment mode selection instruction for a target database, where the deployment mode selection instruction instructs the target database to use a hybrid row-column storage deployment mode or a row-column storage separation deployment mode in a storage system. The computing system determines, based on the deployment mode selection instruction, an execution plan corresponding to the target database, where the execution plan matches a deployment mode indicated by the deployment mode selection instruction. The computing system processes, in the storage system, a database task for the target database based on the execution plan.

Abstract: In a method for storing index metadata associated with stored data, a storage device provides a first metadata storage unit and a second metadata storage unit, wherein a size of the first metadata storage unit is greater than a size of the second metadata storage unit.

Abstract: This application provides a data processing method and a storage device, and belongs to the field of storage technologies. In this application, the storage device performs deduplication and compression based on different granularities, deduplicates data based on a large granularity, and compresses the data based on a small granularity. Therefore, a limitation that a deduplication granularity and a compression granularity need to be the same is removed. A deduplication ratio decrease caused by an excessively large granularity and a compression ratio decrease caused by an excessively small granularity are avoided to some extent, to improve an overall reduction ratio of deduplication and compression.

Abstract: Systems, methods, and apparatuses are described herein that provide a localized temperature solution to a local temperature issue. Sunloading on one side of a vehicle can create a localized heating issue for an occupant on the same side of the vehicle. An air curtain system on the driver's side of the vehicle can detect high sunloading and then direct airflow onto an interior surface of the vehicle such as a door and window. The airflow provides an ambient cooling solution between the occupant and the sun to mitigate the effects of high sunloading. The air curtain system can receive a further input to redirect airflow away from the interior surface and onto the occupant to provide a direct cooling solution to further mitigate the effects of high sunloading. Other features, including sensors and a control unit, for controlling the air curtain system are described herein.

Abstract: A deduplication method and apparatus are provided. In the method, a fingerprint record that includes a plurality of fingerprint record items is first obtained, and at least two first fingerprint record items that include a same fingerprint are then determined from the fingerprint record. For example, the at least two first fingerprint record items each include a first fingerprint, so that deduplication is performed on data corresponding to the first fingerprints in the at least two first fingerprint record items. The at least two first fingerprint record items are deleted, a stub of the first fingerprint is recorded in the fingerprint record, and the stub of the first fingerprint indicates that the first fingerprint is a duplicated fingerprint.
