InfluxDBIOException: java.net.SocketTimeoutException: timeout

I’m using Influx Db java wrapper and adding data in influx db for every 5 seconds with a retention policy of 30 days.

When I’m trying to query the data by sending multiple requests, the timeout exception is seen. Once I clear the db data , the response is received properly.

The exception cause points to this line val results = 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")

All the field values are of Long Type and have values like 2721976000.

Below is response from explain statement of the above query.

I could not find the solution to solve the exception , in the java console logs the response is received properly. Any pointers whether to look at query optimization or cause of exception would be helpful.

Answer

I changed the default timeout of OKHttpClient and the exceptions were not thrown within the particular duration. Missed it earlier as I had passed a different instance of DB.

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)
