 - Online preview mode is mainly used for previewing limited data. Selecting and viewing data directly through SELECT in OpenMLDB CLI or SDKs may result in data truncation. If the data volume is large, it is recommended to use an [export tool](../../tutorial/data_export.html) to view the complete data.
 - SELECT statements in online preview mode currently do not support more complex queries such as `LAST JOIN` and `ORDER BY`. Refer to [SELECT](../../openmldb_sql/dql/SELECT_STATEMENT.html).
 - The server in the online preview mode executes SQL statements on a single thread. For large data processing, it may be slow and may trigger a timeout. To increase the timeout period, the `--request_timeout` can be configured on the client.
-- To prevent impact on online services, online preview mode limits the maximum number of accessed records and the number of different keys. This can be configured using `--max_traverse_cnt` and `--max_traverse_key_cnt`. Similarly, the maximum result size can be set using `--scan_max_bytes_size`. For detailed configuration, refer to the [configuration file](../../deploy/conf.md).

 - 在线预览模式主要用于有限数据的预览，在 OpenMLDB CLI 或者 SDKs 执行 SELECT 直接查看数据可能出现数据截断；如果数据量较大，建议使用[导出工具](https://openmldb.ai/docs/zh/main/tutorial/data_export.html)查看完整数据。
 - 在线预览模式的 SELECT 语句目前不支持 `LAST JOIN` 和 `ORDER BY` 等较复杂的查询，参考 [`SELECT`](https://openmldb.ai/docs/zh/main/openmldb_sql/dql/SELECT_STATEMENT.html)。
 - 在线预览模式服务端均为单线程执行 SQL，对于大数据处理，会比较慢，有可能会触发超时，可以通过在客户端配置 `--request_timeout` 来提高超时时间。
-- 为了防止影响线上服务，在线预览模式控制了最大访问的条数和不同key的个数，可以通过`--max_traverse_cnt` 和 `--max_traverse_key_cnt` 来设置；
