It is possible that an individual Kibana user can submit highly complex queries or a high volume of queries within a short time frame that causes ES to perform poorly for other users?
i have a task is to research technical options available in restricting a users ability to submit further ES queries when there's performance issue.
Are we able to do that in Kibana or any plugins.
Yes. That is a current limitation with Elasticsearch.
Not that I am aware of.
Elasticsearch does have a tasks API that you can use to cancel things, but there is not currently a way to do per-user resource restrictions.
