Parallel execution of multiple scenarios

What ist the best practice for parallel execution of multiple scenarios? For example 30% Users execute scenario1 and 70% users scenario2.

Is the code below the right way or is it better to have one scenario with contional executions of REST calls?

class MySimulation extends Simulation {

val userIdsData = csv(userIdsCSV).queue

val scenario1 = scenario(“Scenario 1”)



val scenario2 = scenario(“Scenario 2”)




setUp(scenario1.inject(rampUsers(30) over (ramp seconds))


scenario2.inject(rampUsers(70) over (ramp seconds))
