Abstract
This application discloses a data replication method and apparatus, a computer device, and a storage medium, and belongs to the field of database technologies. The method includes: adding, when a commitment operation of a transaction is detected, historical state data of the transaction to a data queue; adding at least one piece of historical state data in the data queue to a transmission buffer; and replicating, when a first preset condition is met, the at least one piece of historical state data in the transmission buffer to a cluster device. In this application, a node device does not need to convert an original historical state data format into a log format, and the cluster device does not need to parse a log into an original data format for storage, thereby avoiding a cumbersome log replay procedure, and improving the efficiency of the data replication process.
