Compression Algorithm Verification
Last updated: 2024-10-10 15:24:07
Verification Details
Verify whether the compression algorithms used by the source and target databases are the same. If they are different, a warning is generated. The warning will not block the migration, and the user can ignore the warning to proceed with the task.
Note that when the compression algorithm used by the target database is verified, a random system table will be selected for verification. Since the compression algorithm of the system table does not change after modification, the warning might be inaccurate. If you are sure that the new compression algorithm is used in the target database, you can ignore the warning.
Fixing Solution
The disk size occupied by the same data varies under different compression algorithms. If the user wants the target database to use the same compression algorithm as the source database, modify the compression algorithm of the target database.
