How can i update documents in an index using document\_id in spark. I've seen the option called [es.mappings.id](http://es.mappings.id) but can it be used with multiple fields.

For eg:

I had two fields userid,serialno and i want to create document\_id as %{userid}%{serialno} in spark.

Thanks

I'm able to do for one column using [es.mapping.id](http://es.mapping.id). Can someone tell me how i can include two or more columns as document id

df.write.format("org.elasticsearch.spark.sql").option("[es.mapping.id](http://es.mapping.id)","userid").option("es.resource","testindex/abc").save()
