Is it possible perform bulk insert from Spark to ElasticSearch?
At the moment, I'm using the 'saveToEsWithMeta' method for upserting the data(JavaPairRDD). Is there a way to bulk insert using the \_bulk API? Are there any example that I could take a look?

All the writes in Elasticsearch-Hadoop (including Spark) are done using the
bulk API underneath (through the REST protocol and thus use the `_bulk`
endpoint). Whether you saving 1, 100 or 10K, the procedure is the same.
Btw, I recommend spending some time reading the whole reference
documentation as it covers the architecture pretty well and provides plenty
of examples.

Thank you @costin for your reply. I'll check out the document but were you referring to this; [https://github.com/elastic/elasticsearch-hadoop/blob/master/docs/src/reference/asciidoc/core/spark.adoc](https://github.com/elastic/elasticsearch-hadoop/blob/master/docs/src/reference/asciidoc/core/spark.adoc)

@diplomaticguru Why are you looking at the source and not the official, rendered doc which is available [here](https://www.elastic.co/guide/en/elasticsearch/hadoop/current/spark.html)? The docs are mentioned in the Github readme and on the project homepage.
How did you come across es-hadoop ? It's an honest question since it looks like the reference documentation was not advertised enough and I'd like to address that.
