History of updates modeling

Elastic Stack Elasticsearch
1

I'm newbie to Elasticsearch and I'm wondering about the best way to model this requirement in Elasticsearch: we need to keep the modification history of an object like this:

example{
id;
name;
type;
}

So far, we've followed this approach: every time the object is modified, a new document is inserted into Elasticsearch. I also need to create ratio metrics on the type within a period, considering only the last document of each object within that period, based on a date field added to the object. This makes the query complicated and involves several sub-aggregations.

Have you considered having 2 separate indices - one in which you always store the latest version by performing an update and one where you store each update as a separate document? If you want the current version you efficiently query the first index and if you are looking at changes over time you query the second.
