Can somebody confirm whether Logstash 6.6 (or higher) and the elasticsearch input support aggs?
I'm on 6.6 and while normal queries work, aggs do not. Other topic over the years talk about the same issue and in all cases it appears aggs are not supported after logstash 2.1 or something because the
scoll option messes with aggs queries and on later versions there is no option to disable scroll.
If aggs are not supported this should be clearly indicated on the docs page as there currently is no mention about any limitations at all.
