> I have an Apache Beam streaming job which reads data from Kafka and writes to ElasticSearch using ElasticSearchIO.
> The issue I'm having is that messages in Kafka already have _{{key}}_ field, and using {{ElasticSearchIO.Write.withIdFn()}} I'm mapping this field to document _{{_id}}_ field in ElasticSearch.
> Having a big volume of data I don't want the _{{key}}_ field to be also written to ElasticSearch as part of _{{_source}}_.
> Is there an option/workaround that would allow doing that?
