Elastic Stack Kibana
1

Hello,

I wanted to create a new field either using logstash or elastic search pipeline, can you please help me?

I have JSON mapping as [{"name":"a","age":25},{"name":"b","age":10}] I have field already in my index as name and now I want to create new field age by comparing the name.

Which approach I should follow to achieve this?

Regards,
Mahesh
