I've started playing with transforms - which look very useful.

However, I cannot immediately see that they actually support scripted fields (which I define against a Kibana index). I am trying to sum a couple of them, but values being output simply equal 0 which is not what I expect to see.

Thanks in advance,  
Mark

Transform Jobs support the aggregations and metrics specified in [the documentation](https://www.elastic.co/guide/en/elasticsearch/reference/7.6/put-transform.html#put-transform-request-body).

I didn't check in the latest version, but I think you will have to replicate the scripted fields you need in the metrics as shown [here](https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-metrics-sum-aggregation.html#_script_11).

Some addition: scripts in the `aggregations` part shall be supported if the aggregation itself is supported. Scripting in the `group_by` part - to customize bucketing - will be supported starting with `7.7`, an example can be found in the [PR](https://github.com/elastic/elasticsearch/pull/53167).
