数据同步方法、装置、设备、计算机可读介质和程序产品
By receiving and parsing the full data and accumulating and delaying the expiration time of incremental data, the problem of incremental data not being synchronized during data migration is solved, achieving data synchronization and consistency between the source and target ends and reducing the number of query failures.

AI Technical Summary
During data migration, when the source end adds an expiration time for the keys of incremental data, the migration tool still uses the original expiration time as the standard. This causes the keys of the incremental data to fail to synchronize to the target end, resulting in a large number of times when the incremental data cannot be found when switching to the target end to query the data.
By receiving all data and parsing its synchronization information, accumulating incremental data synchronization information, determining the migration duration, and delaying incremental keys that meet the preset expiration time conditions to increase their expiration time, the incremental data is finally synchronized to the target end.
This reduces the number of times incremental data cannot be found when switching to the target end to query data, ensures data consistency between the source and target ends, and frees up human operation and maintenance resources.
