Hi ,

I'm using Kibana - Elasticsearch Plugin - _Enhanced Table_.  
Issue is I can create computed columns for fields in buckets like terms, filters etc.  
I cannot create computed columns for fields in metrics aggregation like Top hit, Average. etc.

I'm trying to avoid scripted fields to lessen the Load on the system.  
Any idea or turnaround for this issue?

Hello Sandeep,

Scripted fields are indeed what I would recommend here. Alternatively you could add data to each document on ingest using an [enrichment processor](https://www.elastic.co/blog/introducing-the-enrich-processor-for-elasticsearch-ingest-nodes). This way the calculations are all done in advance vs. on the fly.

Regards,  
Aaron
