Hi guys,

I want to paginate the aggregation, so I decided to use partition filter for my case.

1. Is it the right decision?
2. How to assign "num\_partitions " dynamically using "cardinality" in a single query?

We also now have a [composite aggregation](https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-bucket-composite-aggregation.html) too which relies on using a particular sort order and passing an `after` parameter to make repeated calls, each time asking for N results "after" whatever was the last item you unpacked in the last N results.

You can't. We currently don't have a single query that makes these sorts of multiple requests on your behalf.
