Abstract: In a database replication operation, a source end device obtains at least two groups of transaction logs from a log file of a source end database in parallel, where the at least two groups of transaction logs include a first group of transaction logs and a second group of transaction logs. The first group of transaction logs includes at least a first transaction log and a second transaction log that are adjacent to each other, and the second group of transaction logs includes at least a third transaction log and a fourth transaction log that are adjacent to each other, and a generation time point of the second transaction log is earlier than a generation time point of the third transaction log. The source end device then sends the at least two groups of transaction logs to a destination end device.
