Hi  
I'm struggling with one interesting case: we have some data within some patterns. But we don't have any tags: start or end in these documents.  
How I can calculate transaction duration? I'm also see [great article](https://alexmarquardt.com/2020/09/16/using-logstash-and-elasticsearch-scripted-upserts-to-calculate-transaction-duration-from-out-of-order-events/)  
Can You suggest some an examples base on painless scripts or logstash code?  
Thx!

Could you provide an example of your data and what you're trying to do?

I thought about how to aggregate so the best way will be o make documents per filed "number" by logstash or logstash pipelines and calculate duration (how I can do this)? Can You share some examples?

```auto
{
  "message": "abasdsadc",
  "ident": "sample1",
  "@timestamp": "2020-08-18T19:43:36.000Z",
  "number": "1234",
  "x-request": 3423545343432
}

{
  "message": "aasdsadbc",
  "ident": "sample2",
  "@timestamp": "2020-08-18T19:43:76.000Z",
  "number": "1234",
  "x-request": 3423545343432
}

{
  "message": "abasdasdc",
  "ident": "sample3",
  "@timestamp": "2020-08-18T19:43:36.000Z",
  "number": "4556",
  "x-request": 234234234453
}

{
  "message": "aasdsdbc",
  "ident": "sample4",
  "@timestamp": "2020-08-18T19:43:76.000Z",
  "number": "4556",
  "x-request": 234234234453
}

```
