The official reference still has the warning:

**"This functionality is experimental and may be changed or removed completely in a future release."**  
[https://www.elastic.co/guide/en/elasticsearch/reference/5.x/search-aggregations-pipeline.html](https://www.elastic.co/guide/en/elasticsearch/reference/5.x/search-aggregations-pipeline.html)

Is this something that may go away? I think it is great feature and team should harden it and remove the warning. The warning is making it undesirable, otherwise nice feature.

Hi @jay224,

we have a [Github issue to track the state of this "experimental hint"](https://github.com/elastic/elasticsearch/issues/19798) in the docs.

For pipeline aggregations in particular, it says:

> Pipeline Aggregations should remain experimental as we do not yet have enough feedback to know that the API doesn't need big changes. It might be worth adding a note to the experimental tags that we would like to keep the functionality in Elasticsearch but the API may be subject to change as we get more feedback from people using pipeline aggregations in earnest.

So, we don't plan on removing pipeline aggregations but the API is subject to change.
