| `source-id` | 标识一个 MySQL 实例。|
| `enable-gtid` | 是否使用 GTID 方式从上游拉取 binlog，默认值为 false。一般情况下不需要手动配置，如果上游数据库启用了 GTID 支持，且需要做主从切换，则将该配置项设置为 true。 |
| `enable-relay` | 是否开启 relay log，默认值为 false。自 DM v2.0.2 版本起，该配置项弃用，需使用 `start-relay` 命令[开启 relay log](/dm/relay-log.md#开启关闭-relay-log)。 |
| `enable-relay` | 是否开启 relay log，默认值为 false。从 v5.4 开始，该参数生效。此外，你可以使用 `start-relay` 命令[动态开启 relay log](/dm/relay-log.md#开启关闭-relay-log)。 |
| `relay-binlog-name` | 拉取上游 binlog 的起始文件名，例如 "mysql-bin.000002"，该配置在 `enable-gtid` 为 false 的情况下生效。如果不配置该项，DM-worker 将从正在同步的最早的 binlog 文件开始拉取，一般情况下不需要手动配置。 |
| `relay-binlog-gtid` | 拉取上游 binlog 的起始 GTID，例如 "e9a1fc22-ec08-11e9-b2ac-0242ac110003:1-7849"，该配置在 `enable-gtid` 为 true 的情况下生效。如果不配置该项，DM-worker 将从正在同步的最早 binlog GTID 开始拉取 binlog，一般情况下不需要手动配置。 |
| `relay-dir` | 存储 relay log 的目录，默认值为 "./relay_log"。|
