Elasticsearch provides a large set of ingest processors by default. Their number and functionalities can also change from minor versions to extended versions for new scenarios.

Built-in processors
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 the commands, every HTTP client can be used, such as curl (https://curl.haxx.se/), postman (https://www.getpostman.com/), or similar. Use the Kibana console, as it provides the code completion and better character escaping for Elasticsearch.
