Hi! I have 100M item-timestamp pairs for 10M items in index and I would like to find percentiles of item lifetimes. With aggregation I get 10M buckets and using **percentiles\_bucket** I can aggregate buckets into few percentiles. The problem is that ES outputs few hundred Mbytes of buckets and finally the wanted percentiles at the end of the output. How can I reduce the output just to precentiles? I don't need the 10M mid-buckets but only the final result of precentiles. Please see [http://pastebin.com/hCJ9xLir](http://pastebin.com/hCJ9xLir) Regards, Markus Paaso ---

you can use response filtering for that: [https://www.elastic.co/guide/en/elasticsearch/reference/current/common-options.html#\_response\_filtering](https://www.elastic.co/guide/en/elasticsearch/reference/current/common-options.html#_response_filtering) ---
