- * This class as the name suggests is to translate the payload of PUT & POST requests to ElasticSearch (ES) to its
- * compatible syntax, specially compatible with ES v6 or above.
- *
- * For example, data type such as "string" is now replaced by "text" or "keyword".
- *
- * So this class will make those translations reading off from a json configuration file, therefore the configuration
- * can be updated with new translations as and when required without touching the code.
