Robert Coe created BEAM-11284:
---------------------------------

             Summary: Allow for Parent parameter for Parent/Child join - ElasticsearchIO
                 Key: BEAM-11284
                 URL: https://issues.apache.org/jira/browse/BEAM-11284
             Project: Beam
          Issue Type: Improvement
          Components: io-java-elasticsearch
    Affects Versions: 2.25.0
            Reporter: Robert Coe


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
