Hi Team,

I am doing a [composite aggregation](https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-bucket-composite-aggregation.html) and from the docs:

> This aggregation provides a way to stream all buckets of a specific aggregation similarly to what scroll does for documents.

But I am unsure how I can do the streaming as there are no examples in the docs although the docs state the above.

Should I use the scroll API or should I loop and use the [`after`](https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-bucket-composite-aggregation.html#_after) parameter and build a new search multiple times?

Cheers,
