Abstract: Example data processing methods and apparatus are described. In one example method, a control node estimates a data volume of result data obtained after a plurality of second computing nodes execute a data processing task in parallel. The control node determines a quantity of reduce tasks based on the data volume and memory information of a first computing node that executes a reduce task. Each of the plurality of second computing nodes partitions, based on the quantity of reduced tasks, the result data generated after the data processing task is executed, where each partition corresponds to one reduce task. The first computing node performs reduce processing on data obtained after partitioning is performed by the plurality of second computing nodes.

Abstract: An image encoding and decoding method, includes: determining location information of a target reconstructed image block of a current to-be-encoded image block, where the target reconstructed image block is a reconstructed image block used to determine motion information of the current to-be-encoded image block; determining a first transform core pair based on the location information of the target reconstructed image block; and transforming a residual signal of the current to-be-encoded image block based on the first transform core pair, to obtain a transform coefficient.
