Find Segment memory By Field


(Djtecha) #1

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=*

Seems like this kind of works:

GET aws-2018.10.09.02.45-1/_segments?verbose=true
