This disclosure provides a memory management method and apparatus, to perform refined management on a process access status in a physical host, a virtual machine, or a container, and a traffic occupation status of each control group (cgroup). The method can includes a first record table corresponding to a target cache page is used to record all cgroups that have read or written target data from or into the target cache page and a quantity of times that the target data is read or written by all the cgroups, to improve accuracy of a traffic statistics result of a cgroup. In this case, throttling is performed on a first cgroup based on an updated first record table, so that throttling on the first cgroup can be more fair and accurate.

Memory management method and apparatus

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.

Database replication system and method, source end device, and destination end device

This application discloses an arbitration method and a related apparatus. The method includes: detecting, by the first ABS apparatus, first status information of a service module in the first DC; when determining that a communication link between the first DC and the second DC is faulty, obtaining, by the first ABS apparatus, second status information, wherein the second status information is status information that is of a service module in the second DC and that is detected by the second ABS apparatus; and arbitrating, by the first ABS apparatus, a subsequent service providing capability of the first DC based on the first status information and the second status information.
