| TiDB | [`performance.force-init-stats`](/tidb-configuration-file.md#force-init-stats-new-in-v710) | Newly added | Controls whether to wait for statistics initialization to finish before providing services during TiDB startup. |
| TiDB | [`performance.lite-init-stats`](/tidb-configuration-file.md#lite-init-stats-new-in-v710) | Newly added | Controls whether to use lightweight statistics initialization during TiDB startup. |
| TiDB | [`log.timeout`](/tidb-configuration-file.md#timeout-new-in-v710) | Newly added | Sets the timeout for log-writing operations in TiDB. In case of a disk failure that prevents logs from being written, this configuration item can trigger the TiDB process to panic instead of hang. The default value is `0`, which means no timeout is set. |
