Use single feeder file for multiple feeder objects.

Gatling (Open-Source)

Hi I’m using gatling 2.3 and trying to use gatling feeders.
I need to use single feeder file for multiple feeder objects with circular strategy and I need the data, that I get from the feeder to be taken in parallel…
Smth like this:

package test

import io.gatling.core.Predef._
import io.gatling.core.feeder.RecordSeqFeederBuilder
import io.gatling.core.structure.ScenarioBuilder

import scala.concurrent.duration._

class Profile extends Simulation {

  val first_feed: RecordSeqFeederBuilder[String] = csv("test.csv").circular
  val second_feed: RecordSeqFeederBuilder[String] = csv("test.csv").circular

  val first_scn: ScenarioBuilder = scenario("First scenario").repeat(1) {
    feed(first_feed).exec((session: Session) => {
      println("First scenario pick: " + session("value").as[String])
      session
    })
  }

  val second_scn: ScenarioBuilder = scenario("Second scenario").repeat(1) {
    feed(second_feed).exec((session: Session) => {
      println("Second scenario pick: " + session("value").as[String])
      session
    })
  }

  setUp(
    first_scn.inject(rampUsers(5) over 3.seconds),
    second_scn.inject(rampUsers(5) over 3.seconds),
  )
}

With test.csv file like this:

value
1
2
3
4
5

Output is:
First scenario pick: 1
Second scenario pick: 2
First scenario pick: 3
Second scenario pick: 4
First scenario pick: 5
Second scenario pick: 1
Second scenario pick: 2
First scenario pick: 3
Second scenario pick: 4
First scenario pick: 5

The result is exactly the same as if we were reading data from one feeder object. But I need output like this:
First scenario pick: 1
Second scenario pick: 1
First scenario pick: 2
Second scenario pick: 2
First scenario pick: 3
Second scenario pick: 3
Second scenario pick: 4
First scenario pick: 4
Second scenario pick: 5
First scenario pick: 5

Are there any simple solutions for this problem?
