> **Note**: Enabling auto-reconnect is not effective for fetching result sets. Auto-reconnect is only effective for connections established through parameters specifying the database, and ineffective for later `use db` statements to switch databases.
- TSDBDriver.PROPERTY_KEY_RECONNECT_INTERVAL_MS [`reconnectIntervalMs`]: Auto-reconnect retry interval, in milliseconds, default value 2000. Effective only when PROPERTY_KEY_ENABLE_AUTO_RECONNECT is true.
- TSDBDriver.PROPERTY_KEY_RECONNECT_RETRY_COUNT [`reconnectRetryCount`]: Auto-reconnect retry count, default value 3, effective only when PROPERTY_KEY_ENABLE_AUTO_RECONNECT is true.
- TSDBDriver.PROPERTY_KEY_ADAPTER_HA [`adapterHA`]: Whether to enable adapter high availability. Only takes effect when using WebSocket connections. true: enabled, false: disabled. Default is false. When enabled, upon successful connection, the client can obtain the list of all adapter endpoints in the cluster for load balancing. This feature requires TDengine version `3.4.2.0` or higher.

> **注意**：启用自动重连对获取结果集无效。自动重连仅对连接建立时通过参数指定数据库有效，对后面的 `use db` 语句切换数据库无效。
- TSDBDriver.PROPERTY_KEY_RECONNECT_INTERVAL_MS [`reconnectIntervalMs`]：自动重连重试间隔，单位毫秒，默认值 2000。仅在 PROPERTY_KEY_ENABLE_AUTO_RECONNECT 为 true 时生效。
- TSDBDriver.PROPERTY_KEY_RECONNECT_RETRY_COUNT [`reconnectRetryCount`]：自动重连重试次数，默认值 3，仅在 PROPERTY_KEY_ENABLE_AUTO_RECONNECT 为 true 时生效。
- TSDBDriver.PROPERTY_KEY_ADAPTER_HA [`adapterHA`]：是否启用 `adapter` 高可用。仅在使用 WebSocket 连接时生效。true：启用，false：不启用。默认为 false。启用后连接成功就能获取集群所有 `adapter` 列表用于负载均衡，需要 TDengine 版本大于等于 `3.4.2.0` 才能支持此特性。
