Abstract
A data processing method for a distributed system, the distributed system comprising a master storage node and multiple slave storage nodes, includes: storing, responsive to a request for writing a data file, multiple replications of the data file on the multiple slave storage nodes, each of the replications being segmented into data blocks of a same size, wherein the sizes of the segmented data blocks of at least two replications are different; and storing distribution information of the multiple replications.
