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: In one example method, a server obtains compressed data, where the compressed data includes at least a first part and a second part, and where the compressed data is sorted based on popularity values of parts of the compressed data, and a popularity value of a part of the compressed data is greater than a popularity value of a subsequent part of the compressed data. The server decompresses the first part, and decompresses the second part after decompressing the first part, where a popularity value of the first part is greater than a popularity value of the second part.

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.
