Description

It is impossible to index Parent/Child documents using ElasticsearchIO

 

When using parent/child documents in Elasticsearch, child documents must be indexed using the "parent" attribute when using the bulk endpoint.

There needs to be a "parent" attribute on the DocumentMetadata object. I think a FieldValueExtractFn would work really nicely for this
