Hello,

I push some events to elasticsearch with the following structure:

```
{
    "name": "status",
    "value": "active",
    "timestamp": "2018-01-01T00:00:00.000Z"
}

```

And when I receive a new event with the same `name`, like

```
{
    "name": "status",
    "value": "stopped",
    "timestamp": "2018-01-01T01:00:00.000Z"
}

```

I want to update the event `status:active` with a `stopTimestamp` field, like

```
{
    "name": "status",
    "value": "active",
    "timestamp": "2018-01-01T00:00:00.000Z"
    "stopTimestamp": "2018-01-01T01:00:00.000Z"
}

```

The final goal is to show events / transactions on a timeline, and the timeline require the field `stop date`

It is possible to have a document with a start and a stop date base on two previous events ?

Thanks

Martin

If you have lots of unique names to track see discussion on [Distinct count with filter](https://discuss.elastic.co/t/distinct-count-with-filter/155795)

If I understand correctly, you suggest to do another index with my events with start stop from my events with only start.

How I can update automatically my new index ? I need to do an external script or I can have a "built-in" solution ?
