UUID per user and repeat

Hi, I have this scene

def create(): ScenarioBuilder = {
  scenario(name)
    .exec(session => session.set("f2e_mock_service", host))
    .exec(session => session.set("msgId", s"""${UUID.randomUUID().toString}"""))
    .repeat(repeatNumber, "loop_count") {
      exec(CassandraEndPoint.create)
        .pause(Duration(1, SECONDS))
        .exec(CassandraEndPoint.find)
        .pause(Duration(1, SECONDS))
        .exec(CassandraEndPoint.delete)
        .pause(Duration(1, SECONDS))
    }
}

And it´s executed by 50 threads
