Hi,

I am trying to call function fetchFromDruid

def main(args: Array[String]): Unit = {
val res = fetchFromDruid()
  // res comes as null here
}

def fetchFromDruid(): GroupByResponse {
implicit val executionContext = ExecutionContext.Implicits.global
val client = DruidClient("http://localhost:8082")

val query = GroupByQuery(
source = "wikipedia",
interval = new Interval(new DateTime().minusMonths(60), new DateTime()),
dimensions = Seq("countryName"),
descending = true,
granularity = Granularity.All,
aggregate = Seq(
DSL.count("row_count")
),
postAggregate = Seq(
),
limit = Some(100)
)

client(query).onComplete {
case Success(resp) =>
resp.data.foreach { row =>
println(row)
}
      return resp
println("none")
//System.exit(0)
case Failure(ex) =>
ex.printStackTrace()
      return null
//System.exit(0)
}
}

But somehow I am not able to return the response to the caller; i.e the main function. What could be the issue?

Thanks,
Tushar

Hi Tushar! You might want to try Stackoverflow or other Scala help forums. This question does not seem relevant to ScalaPB.
