Too_many_buckets_exception in Elasticseach.7.0.1

Elastic Stack Elasticsearch

Hi,

We came across an error where the query for Dashborad threw for Too_many_buckets_exception. We looked into couple of queries on elastic community and found that in Elasticseach 7.X the value for max_buckets is 10000 and the query is failing because it needs more buckets. If we increase the value to 15000 it works fine by the below command
PUT _cluster/settings
{
"transient": {
"search.max_buckets": <increase that number more than 10000>
}
}

However, we have couple of concern that we would like to clarify:

  1. Previously the limit for max_bucket was unlimited in Elasticseach 6.X, why it is set to 10000 in Elasticseach 7.X ?
  2. What the risk/impact of incresing the max_buckets. What can be the maximum value that can be set to it?
  3. Is there any way to tune max_buckets ?

Thanks and Regards,
