When we are inserting, deleting, or updating a large number of documents, the HTTP overhead is significant. To speed up this process, Elasticsearch allows the execution of the bulk of CRUD calls.
Speeding up atomic operations (bulk operations)
Getting ready
You need an up-and-running Elasticsearch installation, as we described in the Downloading and installing Elasticsearch recipe in Chapter 1, Getting Started.
To execute these commands, HTTP clients can be used, such as curl (https://curl.haxx.se/), postman (https://www.getpostman.com/), or others. I suggest using the Kibana console as it provides code completion and better character escaping for Elasticsearch.
