My understanding is that ElasticSearch provide API through HTTP protocol, the REST(ful) API and also though Transport protocol. I am guessing that Transport API is what is referred to as the Transport Client. I am also guessing that it is a Java API since Elastic run on Java.
While I may be wrong on my assumptions, the use of Java in "Java high-level REST client" confuses me. I know the API is written in Java, is this what is being referred to because normally I would be thinking of a Java client app that interact with Elastic Search via the REST API.
Please help me understand it. Thank you.
