Abstract: A data processing system in embodiments of this application includes a storage layer, a virtual bus, and a service layer. The storage layer includes a plurality of storage devices, and the service layer includes a plurality of services. The storage device and/or service may write registration information into the virtual bus after registration, and the registered storage device or service may discover another device or service. Data may move between the storage devices, between the storage devices and the services, and between the services through the virtual bus. In this way, the plurality of devices can discover and communicate with each other when the devices are not directly connected to each other.

Abstract: This application discloses a data processing method. A first apparatus obtains a first feature of a first data block in storage space. The first feature includes a read/write feature related to the first data block and a read feature of a second data block adjacent to the first data block. The first apparatus inputs the first feature into an access frequency prediction model, to obtain access frequency of the first data block. The access frequency of the first data block is used to determine a type of the first data block. To be specific, in embodiments of this application, future access frequency of the first data block is predicted by using a multidimensional feature of the first data block (the read/write feature of the first data block and a read feature of an adjacent data block).

Abstract: This application provides example data processing methods and systems. One example data processing method includes obtaining a first metadata stream of a first file system, where the first metadata stream is a streaming structure and includes multiple records, and each of the multiple records includes an identifier of a node in the first file system, an identifier of a parent node of the node, and an attribute of the node. A hierarchy of multiple nodes in the first file system is determined based on the first metadata stream.

Abstract: Embodiments of this disclosure provide for a storage device, a cache management method, and related apparatus. The storage device includes at least two levels of storages. The at least two levels of storages include a first-level storage and a second-level storage, and a speed of processing data by the first-level storage is higher than that of the second-level storage. The first-level storage includes at least a first storage area and a second storage area. Hotness values of data stored in the first storage area are within a first hotness value interval, hotness values of data stored in the second storage area are within a second hotness value interval, and the data in the first-level storage is swapped out at a granularity of one storage area based on the hotness values of the data.
