Abstract
In one example, a method includes: receiving a ready-to-split instruction for the to-be-split fragment; sending the ready-to-split instruction to slave servers, so that each of the slave servers obtains data splitting points of the to-be-split fragment, and sends the data splitting points to the master server; when the number of received data splitting points exceeds a first threshold number, sending data splitting points to the control node, so that the control node sends a splitting-storage instruction to the master server; sending the splitting-storage instruction to each of the slave servers, so that each of the slave servers performs splitting-storage on the to-be-split fragment according to the data splitting points, and sends a first message to the master server to indicate completion of the splitting-storage; when the number of received first messages exceeds a second threshold number, performing splitting-storage on the to-be-split fragment according to the data splitting points.
