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: A computing node cluster provided in this embodiment of this application includes a plurality of computing nodes, and the plurality of computing nodes include an aggregation computing node. The plurality of computing nodes are configured to jointly perform a write operation on to-be-written data. Each of the plurality of computing nodes is configured to return a write success after writing partial data in the to-be-written data to a local cache. The aggregation computing node is configured to aggregate the partial data stored in caches of the plurality of computing nodes into aggregated data with consecutive addresses, and write the aggregated data into a storage node.
