 - **Cache Response**: this property is available only when the request method is `GET`. When **Cache Response** is enabled, TiDB Cloud Data Service can cache the response returned by your `GET` requests within a specified time-to-live (TTL) period.
-- **Time-to-live (s)**: this property is available only when **Cache Response** is enabled. You can use it to specify the time-to-live (TTL) period in seconds for cached response. During the TTL period, if you make the same `GET` requests again, Data Service returns the cached response directly instead of fetching data from the target database again, which improves your query performance.
-- **Batch Operation**: this property is visible only when the request method is `POST` or `PUT`. When **Batch Operation** is enabled, you can operate on multiple rows in a single request. For example, you can insert multiple rows of data in a single `POST` request by adding an array of data objects in the `--data-raw` option of your curl command when calling the endpoint.

For better compatibility with other systems, it is recommended that you use the object format `{items: [{dataObject1}, {dataObject2}]}`.
