Hi,  
We are on **ES 6.7**. We previously did not set search.max\_buckets. After having some recent cluster outage, we are leaning towards introducing some limits. One of them is search.max\_buckets.  
I was reading the below documents:  
[https://www.elastic.co/guide/en/elasticsearch/reference/6.7/search-aggregations-bucket.html](https://www.elastic.co/guide/en/elasticsearch/reference/6.7/search-aggregations-bucket.html)  
The maximum number of buckets allowed in a single response is limited by a dynamic cluster setting named `search.max_buckets`. We are planning to set it to 1000. However, we are afraid that this may break some customer who have \>1000 buckets. We are doing an impact study. Are they going to get only 1000 buckets or they are going to get an exception? In 7.x , we know that they are getting an exception. What about 6.7?

Any request that tries to create more than `search.max_buckets` will throw an exception so same behavior as in 7.x.
