 > Periodic full compaction is experimental. It is not recommended that you use it in the production environment. This feature might be changed or removed without prior notice. If you find a bug, you can report an [issue](https://github.com/pingcap/tidb/issues) on GitHub.
 
-+ Sets the specific times for initiating periodic full compaction. You can specify multiple time schedules in an array. For example, `periodic-full-compact-start-times = ["03:00", "23:00"]` indicates that TiKV performs full compaction at 03:00 AM and 23:00 PM, based on the local time zone of the TiKV node.

 + Default value: `[]`, which means periodic full compaction is disabled by default.
