| [`tidb_cdc_write_source`](/system-variables.md#tidb_cdc_write_source-new-in-v650) | Newly added | When this variable is set to a value other than 0, data written in this session is considered to be written by TiCDC. This variable can only be modified by TiCDC. Do not manually modify this variable in any case. |
| [`tidb_enable_plan_replayer_capture`](/system-variables.md#tidb_enable_plan_replayer_capture) | Newly added | The feature controlled by this variable is not fully functional in TiDB v6.5.0. Do not change the default value. |
| [`tidb_index_merge_intersection_concurrency`](/system-variables.md#tidb_index_merge_intersection_concurrency-new-in-v650) | Newly added | Sets the maximum concurrency for the intersection operations that index merge performs. It is effective only when TiDB accesses partitioned tables in the dynamic pruning mode. |
| [`tidb_source_id`](/system-variables.md#tidb_source_id-new-in-v650) | Newly added | This variable is used to configure the different cluster IDs in a [bi-directional replication](/ticdc/ticdc-bidirectional-replication.md) cluster.|

| [`tidb_sysproc_scan_concurrency`](/system-variables.md#tidb_sysproc_scan_concurrency-new-in-v650) | Newly added | This variable is used to set the concurrency of scan operations performed when TiDB executes internal SQL statements (such as an automatic update of statistics). The default value is `1`. |

| [`tidb_ttl_delete_rate_limit`](/system-variables.md#tidb_ttl_delete_rate_limit-new-in-v650) | Newly added | This variable is used to limit the maximum number of `DELETE` statements allowed per second in a single node in a TTL job. When this variable is set to `0`, no limit is applied. |

* TiCDC supports replicating DDL statements in bi-directional replication (BDR) mode (experimental) [#10301](https://github.com/pingcap/tiflow/issues/10301) [#48519](https://github.com/pingcap/tidb/issues/48519) @[okJiang](https://github.com/okJiang) @[asddongmen](https://github.com/asddongmen)

Starting from v7.6.0, TiCDC supports replication of DDL statements with bi-directional replication configured. Previously, replicating DDL statements was not supported by TiCDC, so users of TiCDC's bi-directional replication had to apply DDL statements to both TiDB clusters separately. With this feature, TiCDC allows for a cluster to be assigned the `PRIMARY` BDR role, and enables the replication of DDL statements from that cluster to the downstream cluster.
