We have discussed bulk action via the REST API in the Speeding up atomic operations (bulk operations) recipe in Chapter 4, Basic Operations.

Getting ready

You will need a working ElasticSearch cluster and Maven installed.

The code of this recipe is in chapter_10/nativeclient in the code bundle of this chapter, which is available on Packt's website, and on GitHub (https://github.com/aparo/elasticsearch-cookbook-second-edition). The referred class is BulkOperations.
