我正在使用 Influx Db java 包装器，并每 5 秒在 influx db 中添加一次数据，保留策略为 30 天。
当我尝试通过发送多个请求来查询数据时，出现超时异常。 一旦我清除了数据库数据，就可以正确接收响应。

异常原因指向这一行
val 结果 = influxDB.query(q)
val q = Query(
"select sum(firstCount) as totalFirstCount, sum(secondCount) as totalSecondCount" +
" ,sum(thirdCount) as totalThirdCount, sum(fourthCount) as totalFourthCount " +
"from counters where time > now() - "1h" group by field1 , field2",
"dbname")
所有字段值都是长类型，并且具有类似于 2721976000 的值。
下面是上述查询的解释语句的响应。

我找不到解决该异常的解决方案，在java控制台日志中正确接收到响应。任何是否查看查询优化或异常原因的指示都会有所帮助。
最佳答案
我更改了 OKHttpClient 的默认超时，并且在特定持续时间内没有抛出异常。之前错过了它，因为我传递了另一个数据库实例。
val client = OkHttpClient.Builder()
.connectTimeout(1, TimeUnit.MINUTES)
.readTimeout(1, TimeUnit.MINUTES)
.writeTimeout(1, TimeUnit.MINUTES)
.retryOnConnectionFailure(true)
val influxConnection = InfluxDBFactory.connect("http://localhost:8086", client)
