Fix Space Not Freed After Data Deletion
If space is not released after data is deleted, it could be because the data in the database was not truly deleted but only marked as deleted, still taking up space. This typically happens when the database’s garbage collection mechanism does not promptly execute or when the data is moved to another storage space.
To free up space, you can try the following steps:
- Perform data table cleanup and optimization operations, such as using the OPTIMIZE TABLE command (MySQL) or VACUUM command (SQLite) to free up unused space.
- Manually clean out the junk data in the database, delete records that are no longer needed to free up space.
- If the database supports transaction rollback functionality, you can try executing the ROLLBACK command to undo the uncommitted transaction and release the space occupied by the transaction.
- Adjusting the garbage collection parameters in the database configuration to more frequently clean up unused space.
If none of the above methods are able to free up space, it is recommended to contact the database administrator or technical support from the database vendor for further assistance.
