Abstract
The present disclosure relates to fault repair methods for a database system. In one example method, when working normally, a master node backs up, to a global buffer pool (GBP) node by using a data transmission protocol with a low latency and a high throughput (for example, a remote direct memory access (RDMA) protocol), a modified page generated because of transaction modification. When the master node is faulty, a standby node does not need to replay all remaining replay logs that are not replayed, but only needs to replay redo logs corresponding to a page that does not exist on the GBP node and pages that are not sequentially arranged and obtain the pages.
