Need some wisdom on aggregations.

I have around 230k aggregated IPs I am trying to aggregate and get them to a JSON file.

What would be the best way to do this in the ElasticSearch api?

using the scroll api?  
or just using search?

I'd use the [Composite aggregation](https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-bucket-composite-aggregation.html) to do that. It's essentially an aggregation that can page through the buckets, much like the scroll API can page through search hits.

It will be a lot more memory friendly than trying to aggregate all 230k IPs in one request 🙂
