How to insert data into ElasticSearch from a json file using Java Bulk API?

Elastic Stack Elasticsearch

I have been looking for a definite answer but couldn't find one.
The java bulk api example given expects us to write individual docs into index/type/id.
How to use it to insert data directly from json file?

My json file is as follows:

{ "index" : { "_index" : "test", "_type" : "type1", "_id" : "1" } }
{ "field1" : "value1" }

If you have a file then I'd recommend using the REST Client instead and POST the file content to _bulk endpoint.

I don't think you can do that with the Java high level client (REST or Transport).
Might be wrong though but AFK ATM.
