Abstract
A log fragmentation method is disclosed. A slave database server receives a first log sent by a master database server, wherein the first log includes a data table identifier and match identifier. The slave database server determines a match tree based on the data table identifier of the first log, and fragments the first log based on the match tree. Using a match tree that has been set up, a tree structure of the match tree can be effectively utilized to fragment a log, and the fragmented log has a high degree of concurrency, thus improving the efficiency of log replay.
