+    The `--lock-ddl=REDUCED` option is a [tech preview](./glossary.md#tech-preview). Before using this option in production, test restoring from physical backups in your environment. Additionally, an alternative backup method should be set up for extra safety.
 
 [Percona XtraBackup 8.4.0-2](./release-notes/8.4.0-2.md) adds the [`--lock-ddl=REDUCED`](./xtrabackup-option-reference.md#lock-ddl) option to reduce the time the server remains locked by `xtrabackup` during full and incremental backups. Now, you can execute `Data Definition Language` (DDL) operations while the backup is in progress.
 
 ### Benefits
 
 The `--lock-ddl=REDUCED` option features are as follows:
 
-* Acquire and release the backup lock quickly: The backup process minimizes the time it holds the backup lock, allowing for concurrent DDL operations.

         While we strive to provide accurate performance benchmarks, real-world results may vary depending on your hardware and software configurations.
 
-        The following tables illustrate the approximate time differences between `--lock-ddl=ON` and `--lock-ddl=REDUCED` for local and cloud backups (Amazon S3). The `Improvement (X times)` column shows how many times less the server is locked by xtrabackup using  `--lock-ddl=REDUCED` compared to `--lock-ddl=ON`.

 ### Limitations
 
-* Certain DDL operations consume significant resources, and xtrabackup simultaneously requires I/O to copy and read files. This requirement can increase resource demand from DDL operations during the backup process.
