Abstract: A system time window corresponding to data to be processed is determined based on a data time of the data to be processed when the data to be processed is received in a current system time window. If the data time is within a range of the current system time window, data to be processed having a system receiving time earlier than the synchronization time point is stored, and data to be processed having a system receiving time later than the synchronization time point is immediately processed. If the data time is within a range of a previous system time window, data to be processed having a system receiving time earlier than the closing time point is immediately processed, and data to be processed having a system receiving time later than the closing time point is discarded.

Abstract: A method for processing data after a restart of a node comprises: acquiring, by a processing node, a time point of current legacy data with the longest caching time in a distributed message queue after a restart of the processing node has completed; determining a recovery cycle according to a current time point and the time point of the legacy data; and processing the legacy data and newly added data in the distributed message queue within the recovery cycle. Thus, an interruption of data processing resulting from a restart may be avoided, an impact on the user's feeling may be eliminated, and user experience is improved.

Abstract: A data processing method is disclosed. A system time window corresponding to data to be processed is determined based on a data time of the data to be processed when the data to be processed is received in a current system time window. If the data time is within a range of the current system time window, data to be processed having a system receiving time earlier than the synchronization time point is stored, and data to be processed having a system receiving time later than the synchronization time point is immediately processed. If the data time is within a range of a previous system time window, data to be processed having a system receiving time earlier than the closing time point is immediately, and data to be processed having a system receiving time later than the closing time point is discarded.
