I understand that I can get the semement memory per index in elasticsearch, but is there a way to get the breakdown by field? It would be very useful if I could get the layout of an index and determine if a specific field has a large memory utilization.
This gives me the fielddata in the cache, but I want the field data in the index segments:
GET _nodes/stats/indices/fielddata?fields=*
Something like:
GET _nodes/stats/indices/segments?fields=*
