We have a requirement to set value of id column (unique key) of an index to values coming from data (values of couple of columns from data).
Id column value is set for each document by default. We want to override it with combination of values of 2 incoming columns (data getting loaded in index).
Could you please share if there are any options to achieve this?

When you send the document to Elasticsearch, you can define your own _id field like any other field.
