Hello there,

I have multiple data series which are inter-related, I am not sure how to logically club this and design index and mapping for below:

```
    application-name=Cloobar
      series-1: webtraffic with fields {count, response time}
      series-2: visists with fields { username, ip, ..}
      series-3: transactions with fileds {name, count, response, percentile..}

    application-name=Foobar
      series-1: webtraffic with fields {count, response time}
      series-2: visists with fields { username, ip, ..}
      series-3: transactions with fileds {name, count, response, percentile..}
      series-4: somethings...

```

I wanted to have index created for each application and club the series under indexes as types. But as of ES-7.x, this is deprecated. Then how can i do this?

regards,  
Rajesh
