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.

Abstract: A method includes: A first device sends a first signal to a second device, where the first signal includes a first transmit signal and a first pilot signal; the first device obtains a second signal, where the second signal includes a first self-interference signal, a second pilot signal, and a second receive signal from the second device; the first device extracts jitter information of the first self-interference signal based on the first pilot signal and the second pilot signal; the first device reconstructs a self-interference signal based on the first transmit signal and the jitter information of the first self-interference signal, to obtain a cancellation signal of the first self-interference signal; and the first device cancels the first self-interference signal from the second receive signal based on the cancellation signal of the first self-interference signal.

Abstract: The present disclosure provides example memory fault handling method, computer device, and computer-readable storage medium. One example method includes starting fault analysis for a memory at a first moment, where the fault analysis includes obtaining a current fault analysis result of the memory by analyzing historical fault information, the historical fault information includes fault information of the memory accumulated in a historical time period, and the historical time period is a time period before the first moment or a time period before the first moment and including the first moment. Fault recovery is started for the memory based on the current fault analysis result of the memory.

Abstract: Embodiments of the present disclosure provide example antennas, example microwave devices, and example communications systems. One example antenna includes an antenna body and a filter component. The antenna body includes an antenna aperture and an optical axis. The antenna body is configured to send and receive a radio frequency signal that passes through the antenna aperture. The filter component is located at the antenna aperture and is disposed perpendicular to the optical axis, where the filter component is configured to filter an interference signal in the radio frequency signal. The filter component includes a filter layer and a support component, where the filter layer is formed by a lossy dielectric, where the support component is configured to support the filter layer, and where the filter layer forms a spatial structure similar to a shutter.
