为提高效率，请提供以下信息，问题描述清晰能够更快得到解决：

【TiDB 版本】v4.0.7

【问题描述】通过TiCDC将TiDB的数据复制到MySQL的过程中，发现无索引的表不能被复制。参数如下：

Starting component ctl: /root/.tiup/components/ctl/v5.0.0-rc/ctl cdc changefeed query --pd=http://10.60.79.168:2379 --changefeed-id=sync-test-repl-task

}
}
]
}

要同步的表结构如下：
CREATE TABLE test_no_index (
id int(11) DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_bin；

请帮忙看下原因，多谢。
