IotdbConfig

Struct IotdbConfig 

Source
pub struct IotdbConfig {
    pub base_url: String,
    pub username: String,
    pub password: String,
    pub tls: Option<TlsClientConfig>,
    pub query_timeout_secs: Option<u64>,
    pub breaker: Option<BreakerConfig>,
    pub max_concurrency: Option<usize>,
}

Fields§

§base_url: String§username: String§password: String§tls: Option<TlsClientConfig>§query_timeout_secs: Option<u64>

单次调用超时秒数。0 = 禁用;未配置 = 30 秒。

这是外层预算,与 reqwest 自带的总超时(from_config 建的 client 有 30 秒、new 没有)取先到者。

§breaker: Option<BreakerConfig>

熔断配置;省略则用保守默认(失败率 0.5、窗口 30 秒、打开 10 秒)。

熔断默认开启 —— 保守阈值下只在持续失败时打开。当前没有总开关: BreakerConfig 只有阈值字段,没有 enabled(不许写 {"enabled": false}: 那是反序列化错误,或被 #[serde(default)] 静默吞掉后以为关掉了)。 真要停用,只能把阈值调到不可能触发(如 failure_ratio: 1.1)。

§max_concurrency: Option<usize>

并发上限。0 = 不限并发(与 query_timeout_secs: 0 = 禁用同构); 未配置 = 32。

reqwest 只有 pool_max_idle_per_host(空闲保留数),没有「最大总连接数」 —— 默认无上限意味着并发无背压。上限由本 crate 的信号量实现,不是 reqwest 的旋钮。
