Check Details
Check whether the compression algorithm used in the source database matches that of the target database. If they are different, a warning will be sent. This warning does not block synchronization, and users can ignore it and proceed with the task.
Note that when the compression algorithm used by the target database is checked, an arbitrary system table is selected for checking. Since the compression algorithm of the system table is not changed after the compression algorithm is modified, the warning may be inaccurate. If you are sure that a new compression algorithm has already been used in the target database, the warning can be ignored.
Fixing Method
The disk size occupied by the same data varies under different compression algorithms. If users want the target database to use the same compression algorithm as that of the source, they should modify the compression algorithm of the target database.
