A cache replacement method includes a compute node in a distributed system that sends a first read operation request to a memory node. Then, the compute node separately calculates popularities of the plurality of data objects based on the access information of the plurality of data objects using a first cache replacement algorithm in a plurality of cache replacement algorithms. Finally, the compute node sends a cache replacement request to the memory node based on the popularities of the plurality of data objects, to indicate to replace cold data in the plurality of data objects with a data object to be inserted into the memory node. In this way, the compute node executes the cache replacement algorithm based on global access information.
