Creating a new column from existing columns

Elastic Stack Elasticsearch
1

Dear Elasticsearch community,

I was wondering how I can create a DateTime column from 5 columns (forecasted_year,month,day,hour,minute) as it is shown in the image (after creating a new index).

I am not sure if this should be done when creating the mapping of the index

Thank you!

This should be done at the ingest time
Use for example an ingest pipeline to compose and convert a datetime field
