Abstract: This disclosure provides data processing methods, apparatuses, and systems. In an implementation, a method comprises receiving, by a first data processing unit (DPU), a memory allocation request from a first service process in a computing node that comprises the first DPU, wherein the first DPU stores memory address assignment information that indicates a virtual memory address corresponding to a physical memory allocated by a storage node to the computing node. Determining, by the first DPU based on the memory address assignment information and in the virtual memory address corresponding to the physical memory allocated by the storage node to the computing node, a virtual memory address range assigned to the first service process, and when the first DPU receives a data storage request from the first service process, sending, by the first DPU, a write data request to the second DPU over a communication link between the first DPU and the second DPU.

Abstract: A data reading method, apparatus, and system, and a distributed system, related to the field of storage technologies and can be applied to data reading. The method includes: receiving a data read request sent by a terminal, where the data read request includes a logical address of target data; locally searching, based on the logical address, a first slave node for a latest version of the target data; and, when it is determined that the latest version of the target data has been stored in each of a plurality of slave nodes, sending the latest version of the target data to the terminal. This data reading method, apparatus, system, and distributed system can avoid a rollback of a version of read data.

Abstract: A data processing method in a distributed system is provided. The method includes: A management node splits a to-be-processed data processing request into a map task and a reduce task. A first worker node executes the map task, and writes intermediate data obtained by executing the map task into a shared storage area. The intermediate data is divided into a plurality of partitions based on a quantity of second worker nodes. Each partition belongs to one second worker node. An aggregation node stores, in a centralized manner, intermediate data that belongs to a same partition in the shared storage area. The second worker node obtains intermediate data of a corresponding partition to execute the reduce task.

Abstract: This application provides example methods and systems for supplying power to a device, and example related devices, and relates to the field of energy technologies. One example method includes predicting power load of the device in a first electricity price interval, where the first electricity price interval is a continuous time period in which electricity prices are the same. A power supply policy can then be selected for the device based on the power load of the device in the first electricity price interval, a quantity of stored electric charges of a power storage device at a first moment, and an electricity price at the first moment. Power can then be supplied to the device based on the selected power supply policy.
